5A05 aluminum plate is an Al Mg anti rust aluminum alloy that cannot be strengthened by heat treatment. Cold deformation of the alloy can improve its strength. The plasticity of the annealed state is high, and the corrosion resistance of the alloy is good and acceptable, making it suitable for spot welding, atomic hydrogen welding, gas welding, and argon arc welding.
