Alloy 5083 Pre painted Aluminum Coil

Alloy 5083 Pre painted Aluminum Coil is based on the material Aluminium Alloy 5083. Alloy 5083 Aluminum Plate is a non-heat-treatable, aluminum-magnesium alloy (Mg: 4.0–4.9%) known for exceptional corrosion resistance, especially in marine and saltwater environments. It offers good weldability and formability, making it ideal for structural components, shipbuilding, pressure vessels, and cryogenic applications.

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.
