3A21 aluminum alloy plate sheet
The  3A21 aluminum alloy plate sheet is an Al-Mn alloy. The 3A21 aluminum plate is a widely used rust-proof aluminum. The strength is not high and it cannot be strengthened by heat treatment. Therefore, cold working methods are often used to improve its mechanical properties. The plasticity is still good when it is hardened by semi-cold work, and the plasticity is low when it is hardened by cold work.
