The Introduction of 3A21 Aluminum Sheet Plate

3A21 Aluminum sheet plate is an Al-Mn alloy, which is a widely used anti-rust aluminum. Its strength is not high (only slightly higher than industrial pure aluminum), and it cannot be strengthened by heat treatment. Therefore, cold working methods are often used to improve its mechanical properties; it has high plasticity in the annealed state. Good plasticity when hardened, low plasticity when cold hardened, good corrosion resistance, good weldability, poor machinability.
