3A21 aluminum circles is Al - Mn alloy, widely used as antirust aluminium, strength is not high (only slightly higher than the industrial pure aluminum), can't heat treatment to strengthen, reason often use cold working methods to improve its mechanical properties; In the annealed state with high plasticity, in a cold work hardening plasticity is good, when the cold work hardening plasticity is low, good corrosion resistance, good weldability, cutting performance is bad.
Application
cooking utensils, medical applications, capacitors, road signs
Features
- Good weldability, good tensile strength, elongation rate is better than 25% of the 3003 aluminum plate.
- Smooth, good plasticity and resistance to stress.
