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.

3A21 aluminum alloy plate sheet is mainly used for low load parts that require high plasticity and good weldability, working in liquid or gas media, such as fuel tanks, gasoline or lubricating oil pipes, various liquid containers, and other small load parts made by deep drawing: The wire is used to make rivets. In the fields of aircraft, oil pipelines and food.
