5A02 Aircraft aerospace grade aluminum plate sheet is Al-Mg series anti-rust aluminum alloy, which cannot be strengthened by heat treatment. The alloy has low magnesium content, high plasticity, good formability, and cold deformation can increase its strength. It has high corrosion resistance, fatigue resistance, good plasticity and weldability. Used to make fuel tanks, tubing, etc.
