3A21 Aluminum Plate

3A21 aluminum plate is an Al-Mn series alloy, which is the most widely used anti-rust aluminum. Its strength is not high (only slightly higher than that of industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, cold working methods are often used to improve its mechanical properties; High plasticity in the state, good plasticity during semi-cold work hardening, low plasticity during cold work hardening, good corrosion resistance, good weldability, and poor machinability.

Advantage
1. 3A21 aluminum plate is a typical anti-rust aluminum, which has excellent corrosion resistance and can adapt to humid environments;
2. Good weldability, good tensile strength, and elongation better than 25% of 3003 aluminum plate;
3. Smooth surface, good plasticity and pressure resistance.

Application
Car body skin, roof, floor, etc.
