Aluminum Coil
Aluminum Coil
Product Overview
Aluminum coil, also known as rolled aluminum coil, is a metal product manufactured from aluminum ingots through casting, rolling, and calendering processes, followed by flying shear and stretch-bending treatment . It is a continuous strip of aluminum wound into a coil form, enabling efficient storage, transportation, and subsequent processing .
Our aluminum coils are produced from premium aluminum ingots with precisely controlled alloy compositions, delivering consistent mechanical properties and surface quality across all batches. With thickness typically ranging from 0.2mm to 10mm and widths up to 2500mm, our coils serve as the ideal raw material for industries including construction, electronics, packaging, machinery, and transportation .
Whether you require commercial pure aluminum for decorative applications, high-strength marine-grade alloys for shipbuilding, or specialized tempers for precision forming, our product range provides the optimal solution for your specific requirements.
Key Features
• Lightweight & High Strength: Low density, high strength-to-weight ratio, reducing processing and transportation costs.
• Superior Corrosion Resistance: Natural oxide film protects against moisture, chemicals and salt spray, ideal for indoor/outdoor and coastal use.
• Excellent Processability: Easy to slit, cut, bend and coat, suitable for mass production and complex fabrication.
Cost-Effective & Durable: Long service life, low maintenance, cost-efficient for bulk and long-term applications.
Aluminum Alloy Grade of Aluminum Coil
Alloy Series | Typical Alloy | Introduction |
1000 Series | 1050 1060 1070 1100 | Industrial Pure Aluminum. Of all series, the 1000 series belongs to the series with the largest aluminum content. The purity can reach over 99.00%. |
2000 Series | 2024(2A12), LY12, LY11, 2A11, 2A14(LD10), 2017, 2A17 | Aluminum-copper Alloys. 2000 series is characterized by high hardness, in which the content of copper is the highest, about 3-5%. |
3000 Series | 3A21, 3003, 3103, 3004, 3005, 3105 | Aluminum-manganese Alloys. 3000 series aluminum sheet is mainly composed of manganese. The manganese content ranges from 1.0% to 1.5%. It is a series with a better rust-proof function. |
4000 Series | 4A03, 4A11, 4A13, 4A17, 4004, 4032, 4043, 4043A, 4047, 4047A | Al-Si Alloys. Usually, the silicon content is between 4.5 and 6.0%. It belongs to building materials, mechanical parts, forging materials, welding materials, low melting points, and good corrosion resistance. |
5000 Series | 5052, 5083, 5754, 5005, 5086,5182 | Al-Mg Alloys. 5000 series aluminum alloy belongs to the more commonly used alloy aluminum series, the main element is magnesium, and the magnesium content is between 3-5%. The main characteristics are low density, high tensile strength, and high elongation. |
6000 Series | 6063, 6061, 6060, 6351, 6070, 6181, 6082, 6A02 | Aluminum Magnesium Silicon Alloys. The representative 6061 mainly contains magnesium and silicon, so it concentrates on the advantages of the 4000 series and 5000 Series. 6061 is a cold-treated aluminum forging product, which is suitable for applications requiring high corrosion resistance and oxidation resistance. |
7000 Series | 7075, 7A04, 7A09, 7A52, 7A05 | Aluminum, Zinc, Magnesium, and Copper Alloys. The representative 7075 mainly contains zinc. It is a heat-treatable alloy, belongs to super-hard aluminum alloy, and has good wear resistance. 7075 aluminum plate is stress-relieved and will not deform or warp after processing. |

FAQ
Q: What's the difference between aluminum coils and aluminum sheets?
A: Aluminum coils are continuous rolls, suitable for mass production and automated manufacturing; aluminum sheets are cut to length. Both are made of the same material, just with different shapes to suit different processing needs.
Q: How do I choose the right alloy for my application?
A: Basic principles: Choose the 1xxx series for high formability and conductivity; choose the 3xxx series for medium strength and resistance to moisture; choose the 5xxx series for marine environments and high strength requirements; choose the 6xxx series for heat-treatable strengthening and good machinability.
Q: Can you provide non-standard sized aluminum coils?
A: Yes. We accept custom orders, including non-standard widths, thicknesses, inner diameters, and coil weights. Specific details require discussion of the minimum order quantity.
Q: What is the tempered state, and how do I choose it?
A: The tempered state indicates the material's processing method and mechanical properties. O represents the annealed state (softest), H represents the work-hardened state (H14 semi-hard, H18 fully hard), and T represents the heat-treated state (T6 highest strength). The choice depends on your forming requirements and the strength needs of your final application.
