The Introduction of 3A21 Aluminum Sheet/Plate:

3A21 Al-Mn aluminum alloy, 3A21 aluminum plate sheet is a kind of widely used anti rust aluminum, the intensity is not high (only slightly higher than that of pure aluminum), can be strengthened by heat treatment, so we often use cold processing methods to improve its mechanical properties; in the annealed state have high plasticity, in the semi cold hardening plastic is good, when the low plasticity of cold hardening, good corrosion resistance, good weldability, poor machinability.

Performance Advantages of 3A21 Aluminum Sheet/Plate:

1, 3A21 aluminum plate sheet is a typical antirust aluminum, with excellent corrosion resistance, can adapt to the humid environment;

2, good weldability, good tensile strength, elongation is better than 3003 aluminum plate 25%;

3, smooth surface, good plasticity, pressure resistance;

4, the company has a semi continuous casting production line of 6, continuous casting and rolling production line of the 10, other large-scale processing equipment 44 units, the annual output of up to 450 thousand tons;
