3A21 aluminum plate is Al-Mn alloy, 3A21 aluminum is a widely used anti-rust aluminum, the strength is not high (only slightly higher than the industrial aluminum), can not be heat treatment strengthening, so often cold processing methods to improve its mechanical properties; State of high plasticity, hardening in the semi-cold when the plastic is still good, cold work hardening plasticity is low, good corrosion resistance, good weldability, poor machinability.
Application
Body skin, roof, floor
Features
- 3A21 aluminum is a typical anti-rust aluminum, with excellent corrosion resistance, can adapt to the humid environment.
- Good weldability, tensile strength, elongation is better than 3003 aluminum 25%.
- The surface smooth, plastic, and pressure.
