3A21 aluminum alloy is an Al-Mn series alloy. 3A21 aluminum alloy is the most widely used anti-rust aluminum. It has low strength (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment, so cold working methods are often used to improve its mechanical properties; It has high plasticity in the annealed state, good plasticity in semi-cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability, and poor machinability.
Application Area
3A21 aluminum are mainly used for welding that requires high plasticity and good weldability, such as aerospace, military equipment, tooling and fixtures, automobiles, transportation, production of propellant tanks, welding of structural cabin skins, end frames, brackets, etc. Parts, as well as conduits that work in corrosive media.
