Introduction
3A21 aluminum sheet（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.

Applications
3A21 aluminum alloy
3A21 aluminum alloy is mainly used for applications which requiring higher plasticity and good weldability, such as fixtures, automotive, transportation, production of propellant tank.
3A21 aluminum sheet
welded structure pods skin, end frames, frame and other welding members, as well as catheters and other members which work in corrosive media.
Advantage of Chenggong 3A21 aluminum sheet
Anti fatigue strength, high shear strength, and high elongation.
3a21 aluminum plate has excellent corrosion resistance and can adapt to humid environments.
The finished product layout is neat and free from defects such as bumps, highlights, scratches, etc.
Strong corrosion resistance and stress corrosion cracking.
