Alloy 5754 Pre Painted Aluminum Coil

Alloy 5754 Pre Painted Aluminum Coil used the Aluminium Alloy AA5754 as base material. It is is a non-heat-treatable member of the 5xxx series, characterized by its high magnesium content (2.6–3.6%), which provides excellent corrosion resistance, formability, and weldability. Developed for applications requiring a balance of strength and ductility, it is widely used in marine environments, automotive structures, pressure vessels, and cryogenic systems.

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.
