Differences between DC Casting and CC Casting
The thickness of 0.7 mm refers to the thickness of aluminum coils, commonly used in various industries for roofing, cladding, and fabrication applications. So, comparing the quality of aluminum coils with a 0.7 mm thickness through some details on DC and CC Casting could help us get a clear and reasonable result.
DC (Direct Chill) Casting:
- The direct chill casting process produces a magnificent and uniform aluminum grain structure.
- This fine-grain structure gives aluminum strength, formability, and corrosion resistance compared to other casting methods.
- Direct chill-casting aluminum coils are often used in applications that require deep drawing or complex forming, such as automotive body panels, heat exchangers, and food/beverage cans.
- The 0.7 mm thickness is on the thinner end for DC casting aluminum. However, this gauge is still suitable for many formed and fabricated components.
CC casting (Continuous Casting):
- Continuous Casting is a more economical process than DC casting.
- CC-casting aluminum billets, blooms, or slabs have a slightly larger grain structure than DC-casting. However, it is still suitable for a wide range of applications.
- CC-casting aluminum coils with a thickness of 0.7 mm are commonly used for general sheet metal fabrication, roofing, siding, and other building/construction applications.
- The 0.7 mm thickness provides a good balance of formability, strength, and lightweight properties for these types of uses.
In summary, DC-casting aluminum coils have superior mechanical properties and surface quality compared to CC-casting but at a slightly higher cost. Even so, neither DC nor CC-casting aluminum coils with a thickness of 0.7 mm can exhibit good flatness, surface quality, and dimensional tolerance and can be used in different applications depending on the project’s specific requirements.
The choice between the two kinds of production technology depends on the end product’s specific performance requirements, economic considerations for the specific application, and customer requirements. DC casting is preferred when superior formability and strength are needed. In contrast, CC casting is more economical for less demanding applications.
Advanced Color-Coated Process
Polyester-coated pre-coating Technology(PE Coating)
The polyester coating is a kind of anti-UV UV polyester resin coating; its primary component uses polymers containing ester bonds in the main chain as monomers, adding alkyd resin and an ultraviolet absorber. After baking polyester coating on the surface of aluminum (aluminum sheet, aluminum coil) many times, it forms a solid film with protection and decoration. The polyester coating protects color-coated aluminum products (aluminum sheets, aluminum coils) from exposure to the atmosphere due to temperature differences, freeze-thaw cycles, corrosive gases and microorganisms, ultraviolet radiation, wind, rain, frost, and snow.
In addition, the polyester coating can give color-coated aluminum substrate products rich color. According to gloss, the polyester coating can be divided into matte and highlight series. Therefore, the color-coated aluminum coil not only has good gloss and smoothness but also superior texture and feel and can also increase the sense of layer and three-dimensionality. It is especially suitable for interior decoration and advertising boards.
polyvinylidene difluoride coating technology(PVDF Coating)
Fluorocarbon coating is PVDF resin. It mainly refers to vinylidene fluoride homopolymer or vinylidene fluoride and other small amounts of fluorinated vinyl monomer copolymer coatings. The fluoric acid-base material with a fluorine/carbonization bond has a stable and firm chemical structure, which makes the physical properties of fluorocarbon coatings different from those of general coatings.
Fluorocarbon coatings can be divided into traditional fluorocarbon coatings and nano-fluorocarbon coatings according to the film formation structure of the surface. In 1965, the Pennwalt Chemical Company of the United States, for the first time, used fluorocarbon paint for the coating of indoor and outdoor aluminum in high-grade buildings, a wide range of color selectivity, solemn appearance, and durability for many magnificent curtain wall buildings around the world added luster.
In addition to the wear and impact resistance in terms of mechanical properties, it also shows excellent and long-term fading resistance and UV resistance in harsh climates and humid environments. After high-temperature grilling, the molecular structure of the coating is tight, and the machine has superior weather resistance. The coating manufacturer’s guarantee of the service life of the coating began to be 10 years, 15 years to guarantee more than 20 years.
American research institutions have tested and compared fluorocarbon, super, and general coatings. The samples of the coatings were exposed to hot sunlight in Florida, the United States, and exposed to the harsh environment of humid salty air for 12 years, which proves that the stability and durability of fluorocarbon coatings are 30%-80% higher than those of the other two coatings. Fluorocarbon coatings ensure that they can be used in various harsh environments. It is especially suitable for indoor and outdoor decoration in public places, commercial chains, exhibition advertising, and other decorations and displays.

In the product application of the 3003 aluminum coil, there are some common misunderstandings and pitfalls. The following are some prominent examples:
Misunderstandings
- Application Limitations.
- Some may think the 3003 aluminum coil is only suitable for specific fields, such as construction or transportation. However, because of its excellent performance, it has many applications in many other fields, such as electronic appliances, the packaging industry, furniture, and home appliances.
- Corrosion and rust problems.
- Some think metal materials, such as 3003 aluminum rolls, are prone to corrosion and rust. However, this is a myth. 3003 aluminum coil is rust-proof aluminum, mainly composed of aluminum, manganese, and other alloying elements, with good corrosion resistance. It is especially suitable for construction, transportation, and other fields.
- Improper storage.
- For thermal insulation aluminum coils, especially 3003 aluminum coils, if you ignore waterproof and moisture-proof insulation when storing them, it may lead to rust or corrosion of the aluminum coil, affecting its performance.
- Construction is complicated.
- Some people think that materials made of metal are complex and challenging to construct. However, the 3003 aluminum coil for the structure of the building is low. The design and construction are more convenient and straightforward and can be adapted to various roof modeling. Moreover, due to its lightweight, the use of simple accessories makes the overall installation process relatively straightforward, significantly reducing the strength of the construction and shortening the construction period.
- Poor stability.
- Some think the metal roof plate of the 3003 aluminum coil will be very noisy on rainy days or blown away in strong winds. However, the 3003 aluminum coil is powerful, has high stability, can withstand storms, earthquakes, hail, and other impacts, and has wind resistance up to 120mph.

The 3003 metal panel is closely connected with the overall lightning protection system of the structure, which can entirely remove the problems of lightning damage and electrostatic accumulation, adding a layer of lightning protection for the building.
Pitfalls
- Material shrinkage
- When purchasing aluminum coil materials, sometimes you encounter a low-price trap. To reduce costs, some manufacturers may reduce the alloy content or the thickness of aluminum, leading to a decline in the load-bearing capacity of aluminum profiles. Long-term use may result in bending deformation or even fracture.
- Low price temptation
- Low prices are often accompanied by quality risks when buying aluminum coil materials. Low prices may mean that the quality of the material could be better, and it may even be defective or recycled materials reprocessed.
- Quality problems
- There may be some quality defects in the production process of aluminum coil materials, such as non-metal pressing, bruising, warping, folding, and so on. These defects may affect the performance and service life of the aluminum coil, so when choosing the aluminum coil material, it is necessary to check its quality carefully.

- The thermal expansion coefficient of the 3004 aluminum coil is slightly lower than 3003. Still, the melting point is slightly higher, and the anti-wear ability is better.
- Chemical Component
- 3003 aluminum coil mainly contains aluminum, manganese, and other elements, of which the manganese content is 1.0-1.5%.
- In addition to aluminum, manganese, and other elements, the 3004 aluminum coil also contains magnesium, which is 0.8-1.3%.
- Processing Properties
- 3003 aluminum coil has good plasticity and toughness, and the processing and molding process is easier to handle.
- 3004 aluminum coil is brittle, so it needs to be more careful when processing, as processing difficulty is relatively high.
- Corrosion Resistance
- The corrosion resistance of 3004 aluminum coils is generally more substantial than that of 3003 aluminum coils. This is because, in addition to aluminum, manganese, and other elements, the 3004 aluminum coil also adds magnesium; adding these alloying elements enhances its corrosion resistance. Especially for resistance to acid rain, salt water, and other external environmental erosion, the 3004 aluminum coil shows good corrosion resistance. However, it should be noted that corrosion resistance is also affected by many factors, such as material surface treatment and use environment, so it is necessary to choose comprehensively according to the specific situation in practical applications.
- Application Performance
- 3003 aluminum coil has excellent formability, good corrosion resistance, and relatively low strength. It is commonly used to produce curtain walls, automobile parts, radiators, kitchenware, etc.
- The 3004 aluminum coil has relatively high strength and hardness while maintaining good corrosion resistance. It is often used to manufacture products requiring higher corrosion and wear resistance, such as automobile shells and decorative panels.
- Price
- Due to the higher proportion of magnesium in the 3004 aluminum coil, its manufacturing cost is relatively high. This results in a slightly higher processing price than the 3003 aluminum coil, an essential economic factor to consider.
Which aluminum coil is better depends on the specific application scenario and requirements. If higher strength, hardness, and corrosion resistance are required, a 3004 aluminum coil is more suitable. Suppose more attention is paid to formability and corrosion resistance, and there are specific cost requirements. In that case, a 3003 aluminum coil may be a better choice.
Both 3003 and 3004 aluminum coils are versatile materials that can be adapted to the specific needs of automotive parts. Their unique properties make them suitable for a wide range of applications in automotive manufacturing.
3003 aluminum coil, with its high flexibility, strength, and corrosion resistance, finds extensive use in automotive manufacturing. It is well-suited for parts requiring high strength and good formability, such as body panels, fuel tanks, coolers, air conditioners, and heat exchangers.

On the other hand, the 3004 aluminum coil is a staple in automobile manufacturing, thanks to its enhanced strength and other benefits. Its lightweight nature, corrosion resistance, and good formability make it a versatile material. Its superior strength, in particular, makes it an ideal choice for producing automotive parts that require higher strength, such as body exterior panels, wheel covers, and body skeletons.
When choosing between 3003 and 3004 aluminum coils, it’s essential to consider the specific application needs and design objectives. If the auto parts require higher strength and hardness or must withstand more significant pressure and impact, then the 3004 aluminum coil may be the better choice. Conversely, if formability and corrosion resistance are more critical, and cost is a consideration, the 3003 aluminum coil may be more suitable. The performance of these two materials should be carefully evaluated, and the best choice should be made based on the specific requirements.
Both the 3003 and 3004 aluminum coils, part of the AL-Mn series alloys, possess unique properties that make them ideal for food packaging. These aluminum packaging materials exhibit excellent barrier properties, oxidation, and moisture resistance. They effectively prevent the oxidation and deterioration of food, medicine, and other easily oxidized substances, and also protect against moisture erosion, thereby extending the storage time of goods. Their alignment with food safety and hygiene standards, high and low-temperature resistance, and green environmental protection, further enhance their suitability for food packaging materials.
Therefore, the versatility of 3003 and 3004 aluminum coils makes them ideal for use as food-grade materials.
Specifically, the 3003 aluminum coil has excellent forming performance, and its mechanical properties are manifested as tensile strength σb (MPa) between 95 and 210 and conditional yield strength σ0.2 (MPa) ≥170. Secondly, the 3003 aluminum coil also has excellent corrosion resistance to the atmosphere, freshwater, seawater, food, organic acids, gasoline, neutral inorganic salt aqueous solution, etc. At the same time, the 3003 aluminum coil has excellent barrier properties for water, air (oxygen), light, and microorganisms, which are important factors leading to food deterioration. Therefore, the corrosion resistance, formability, and excellent barrier properties of the 3003 aluminum coil provide good protection functions for food. Because of this, 3000 aluminum rolls are suitable for kitchenware, food packaging, food, and chemical products processing and storage devices, as well as other scenarios, such as food cans, food containers, and aluminum foil lunch boxes.
The 3004 aluminum coil, with its enhanced formability and corrosion resistance, outperforms the 3003 aluminum coil. Its chemical composition is similar to 3003, but adding more magnesium (Mg: 0.8 ~ 1.3) offers higher strength and hardness while maintaining good corrosion resistance. The 3004 aluminum coil has many application prospects in food packaging, especially in higher corrosion and wear resistance scenarios. Additionally, 3004 aluminum foil, as a prefabricated food box material, boasts oxidation and corrosion resistance, is lightweight, has high strength, is easy to process, has environmental protection, and is recyclable. These advantages effectively protect prefabricated dishes from oxygen, moisture, and microbial erosion, thereby extending the shelf life of food.
Therefore, when choosing a packaging material, it’s crucial to consider the specific needs of food packaging and the use environment. Whether you need higher corrosion resistance and strength (3004 aluminum coil) Or you prioritize formability and cost (3003 aluminum coil), always ensure that the chosen material meets the relevant food safety standards and regulations. Adhering to these standards is vital to providing the safety and reliability of aluminum food packaging materials.
The price of the 3003 aluminum coil will be affected by many factors, such as market supply and demand, raw material prices, and processing technology. Therefore, the specific price of an aluminum coil needs to be determined according to several factors. The multiple factors that the price limitation include the following aspects:
- Basic Material Fee.
- Aluminum is the base material of aluminum coils, and the price will vary with different specifications and thicknesses. Generally speaking, the thinner the thickness, the higher the price; the more significant the corresponding length and width, the higher the price. In addition, there will be price differences between aluminum rolls from different manufacturers.
- Alloy Composition.
- Understanding the alloy composition’s role in the performance of the aluminum coil is crucial. It influences factors such as strength and corrosion resistance, empowering buyers to make informed decisions based on their needs and budget.
- Manufacturing Technology.
- The production process of the aluminum coil plays a significant role in determining its price. For instance, the domestic aluminum coil is primarily made from waste materials through melting, casting, and rolling. In contrast, the imported aluminum coil is typically made from raw aluminum alloy through melting and casting. Understanding these differences in production processes and raw material costs helps buyers comprehend why the price of imported aluminum coils is usually higher than that of domestic aluminum coils.
- Surface Coating.
- The surface of the aluminum coil needs to be coated, and different coating materials and coating thicknesses will affect the price. PVDF coating is more expensive but has better weather resistance and longer service life. The cost of PE coating is lower, but the weather resistance could be better than that of PVDF coating.
- Market Demand and Supply.
- Market demand and supply also affect the price of aluminum coils. When demand is more significant than supply, prices may rise. Conversely, when supply is more significant than demand, prices may fall.
The price of aluminum coil is influenced by many factors. When purchasing aluminum rolls, it’s crucial to consider these factors and select the type that best fits your requirements and budget. We strongly encourage each customer to engage in detailed communication and negotiation with the supplier to ensure the best price and service.
DC and CC Casting, two crucial methods in aluminum production, refer to different casting ways of producing aluminum billets, blooms, or slabs. Casting is a process of shaping ingots by pouring the liquid metal into a mold, followed by solidification. Casting is a metal treatment detail produced by pouring metal into a mold. In some cases, casting is the only method of shaping a metal or alloy.
DC stands for Direct Chill Casting. It is a vertical semi-continuous casting process for manufacturing cylindrical or rectangular ingot/billet for non-ferrous metals such as aluminum and copper alloys. The widely used casting process involves solidifying molten metal in a water-cooled mold, resulting in an aluminum ingot with a fine-grain structure. So, the direct chill casting aluminum billets, blooms, or slabs are suitable for deep drawing or complex forming. Therefore, extrusion, rolling, or forging technology can further process direct chill-casting aluminum ingot.
The DC casting process is the most common application for casting aluminum billets, and more than half of the world’s aluminum billets, blooms, or slabs are cast using direct chill casting. This widespread use underscores the process’s importance in the global aluminum production industry.
CC casting, or Continuous Casting, is a process that continuously solidifies molten metal into ‘semi-finished’ billets, blooms, or slabs. It’s a method that’s not only used for casting aluminum billets but also gaining popularity in the aluminum industry.
The lower inherent cost of continuous, standardized production and improved process and quality control through automation allows continuous casting technology to produce better-quality metal profiles at a lower price.
This process is most commonly used for casting steel (by tonnage). So do aluminum and copper. In the aluminum industry, CC-casting aluminum billets, blooms, or slabs are often used to produce general-purpose aluminum rolls.
Yes, specific industries tend to prefer DC-casting aluminum coils over CC-casting, especially for applications that require the enhanced mechanical properties and surface quality of DC-casting material. This preference is driven by the numerous benefits that DC-casting offers, such as:
Automotive Industry:
- The automotive sector is a significant consumer of DC-casting aluminum coils.
- The high strength, formability, and surface finish of DC casting are crucial for producing complex body panels, structural components, and heat exchangers.
- Automakers value the tight dimensional tolerances and consistent quality of DC-casting aluminum.
Aerospace and Defense:
- The superior mechanical properties of DC-casting aluminum are essential for aerospace and defense applications.
- Components like airframe structures, engine parts, and defense equipment demand the high strength-to-weight ratio of DC casting.
- The enhanced fatigue life and corrosion resistance are also meaningful in these industries.
Packaging:
- Beverage cans, food containers, and other tight-tolerance packaging applications often utilize DC-casting aluminum.
- Fine grain structure and smooth surface finish are critical for deep drawing these products.
- Consistent thickness and flatness ensure good sealing and performance.
Electronics:
- Electrical enclosures, heat sinks, and other electronic components may use DC-casting aluminum coils.
- The higher strength allows for thinner designs without compromising performance.
- Smooth surfaces are essential for aesthetic appeal and thermal management.
While more costly, the enhanced properties of DC-casting aluminum make it the preferred choice in industries with stringent performance requirements. However, improved performance and durability often offset this higher cost, making DC-casting a cost-effective solution for many applications. CC casting remains suitable for more general applications where the premium properties of DC casting are not as critical.
The appropriate aluminum coil thickness selection must be determined according to the specific application scenario and requirements. Thinner aluminum rolls are generally suitable for occasions where weight and cost must be reduced. In comparison, thicker aluminum rolls have better strength and stability. When selecting, it is recommended to consult a professional salesperson or engineer to ensure that the most suitable aluminum coil thickness is specified.
Factors Affecting the Weight of Aluminum Rolls
The weight of an aluminum coil depends on its material density, length, width, and thickness. With the exact specifications for aluminum coils, different manufacturers may produce a specific difference in weight, which can be measured by a weight meter and other equipment. At the same time, the coating material and treatment process in the production process of the aluminum coil will also have a particular impact on its weight. Generally, the weight of the standard aluminum coil is between 500 and 5000kg.
Aluminum coil weight calculation formula
Aluminum coil weight (kg) = aluminum coil length (m) × aluminum coil width (m) × aluminum coil thickness (m) × aluminum coil density (kg/m³)
Among them, the density of the aluminum coil is 2.7×103kg/m³.
For example, if the aluminum coil’s specifications are a width of 1 m, a thickness of 0.3 mm, and a length of 100 m, then the weight can be calculated according to the following formula: weight = 2.7 g/cm3 x 10,000cm x 100 cmx0.03 cm = 81,000 g = 81Kg.
Notes: When calculating the weight of the aluminum coil, it is necessary to pay attention to the unity of the unit, such as the length and width need to be converted into centimeters or meters.
Weight reference value corresponding to standard specifications of aluminum coil
The following are common aluminum coil weight reference values for reference only:
- The weight of the 1.0mm thickness aluminum coil specification is about 2.7kg/m², and 1 ton of aluminum coil can be divided into about 370 sheets, with a width of 1.25 meters and a length of 10 meters each.
- The weight of the 0.6mm thickness aluminum coil specification is about 1.5kg/m², and 1 ton of aluminum coil can be divided into about 667 sheets, with a width of 1.25 meters and a length of 10 meters each.
The above data is for reference only. The specific weight must be calculated and measured according to the aluminum coil’s specifications.
When calculating the length of the aluminum coil, it is necessary to understand the specific specifications. Generally speaking, the specifications will indicate the aluminum coil’s width, thickness, and length. If only partial information about the weight and specifications of the aluminum coil is known, the size of the aluminum coil can be reversed.
For example, if the aluminum coil specification is 800mm wide, 0.5mm thick, 100kg in weight, and the density of aluminum is known to be 2.7g/cm³, then its length can be calculated as follows:
- Step1: Calculate the aluminum coil area
Area = 800mm x 0.5mm = 400mm² = 0.04m²
- Step2: Calculate the aluminum coil length
Length = 100kg / 2.7g/cm³ / 0.04m² = 925.93m
Therefore, the length of the above aluminum coil is 925.93m.
Notes: When calculating the length of the aluminum coil, please pay attention to the distinction between standard specifications and the correct application of the weight calculation formula.
