Overview of rust-resistant aluminum-manganese alloys
3A21 aluminum plate for Al-Mn alloy, 3A21 aluminum plate is the most widely used a kind of rust-proof aluminum, the strength is not high (only slightly higher than industrial pure aluminum), can not be strengthened by heat treatment, so cold working method is often used to improve its mechanical properties; It has high plasticity in annealing state, good plasticity in semi-cold hardening, low plasticity in cold hardening, good corrosion resistance, good weldability, and poor machinability.

Typical Uses
3A21 is mainly used for high plasticity and good weldability, such as aerospace, military equipment, fixture, automobile, transportation, the production of propellant tank, welding structural cabin skin, end frame, support and other welding parts, as well as in corrosive media working conduit.

Heat treatment process
1. Uniform annealing: heating 510~520℃ : insulation 4~6h; Air cooling.
2. Rapid annealing: heating 350~500℃; Depending on the effective thickness of the material, the insulation time is 30~120mm; Air or water cooling.
3. High temperature annealing: heating 350~500 finished product thickness ≥6mm, holding time 10~30min, < omm, heat through until: air cooling.
4. Low temperature annealing: heating 250 ~ 300℃ : holding time is 1~3h; Air or water cooling.
Status: Aluminum and aluminum alloy molded plate (0.6 ~ 0.8 mm, HX8 state)
