Alloy 8011 Color Coated Aluminum Coil

8011 Alloy color coated aluminum coil are based on the Aluminium 8011 material, it is an 8xxx series aluminium alloy primarily composed of aluminium with small additions of silicon and iron. It belongs to the non-heat-treatable alloys, meaning its mechanical properties are improved through cold working rather than heat treatment.

Advantages

Highest Purity in 1xxx Series

Reduces contamination risks in sensitive applications (e.g., pharmaceuticals, high-purity electronics).

Unmatched Formability

Ideal for ultra-thin gauge products (e.g., foil as thin as 6 microns) and complex geometries.

Cost-Effective Purity

Lower production cost than specialty high-purity alloys (e.g., 1100-H18) while maintaining critical properties.

Environmental Friendliness

100% recyclable with minimal energy loss, aligning with sustainability goals.
