5A02
5A02 is an Al-Mg rust-proof aluminum alloy and cannot be strengthened by heat treatment. This alloy has a lower magnesium content and is more ductile.
High, well formed, and low in strength, but higher than 3A21 alloy. Cold deformation can increase its strength, while reducing plasticityLow. The alloy has good corrosion resistance and is suitable for use in marine environments. The alloy has good weldability.
