3A21 aluminum sheet is mainly used for applications which requiring higher plasticity and good weldability, such as aerospace, military equipment, fixtures, automotive, transportation, production of propellant tank, welded structure pods skin, end frames, frame and other welding members, as well as catheters and other members which work in corrosive media.
Higher plasticity after annealing
Good corrosion resistance
Weldability
Introduction
3A21 aluminum alloy（Al-Mn）is an anti-rust aluminum which has a wildly application, the strength is not very high (only higher than industrial aluminum), and cannot be heat treated, so cold working method is usually used to improve their mechanical properties. It has a higher plasticity after annealing and it is better than in the semi-cold hardening. When it is cold-hardening, the plasticity and machinability are low, but it has good corrosion resistance and weldability.
