5.FAQ
Q1:Can the thickness and width of aluminum coils be customized?
A1:Customization is supported. The conventional thickness is 0.2–5.0mm and width is 500–1800mm. Special specifications can be adjusted according to customer needs.
Q2:What are the precautions for aluminum coil storage?
A2:Store in a dry and ventilated warehouse, avoid rain and exposure to sunlight; stack different alloy grades separately to prevent mixing; regularly check for oxidation spots on the surface.
Q3:Which is more suitable for auto lightweighting, aluminum coil or steel coil?
A3:Aluminum coil is more suitable. Its density is much lower than steel. Replacing steel with aluminum can significantly reduce body weight while ensuring structural strength, thus reducing auto fuel consumption.
Q4:What surface treatments can be applied to aluminum coils?
A4:Treatments such as anodizing, spraying, film coating and wire drawing are available to improve surface aesthetics and corrosion resistance, meeting the needs of different application scenarios.
