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.
