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.
