3A21 is a type of rust-resistant aluminum, and its chemical composition is basically the same as 3003. It can be interchangeably used in most applications.
The strength of 3A21 Aluminum Sheet is slightly higher than that of industrial pure aluminum. It cannot be heat-treated for strengthening, but it has high plasticity in the annealed state. It has excellent corrosion resistance and good welding performance.
