The Introduction of 3A21 Aluminum Sheet Plate

3A21 Aluminum sheet plate is an Al-Mn alloy, which is a widely used anti-rust aluminum. Its strength is not high (only slightly higher than industrial pure aluminum), and it cannot be strengthened by heat treatment. Therefore, cold working methods are often used to improve its mechanical properties; it has high plasticity in the annealed state. Good plasticity when hardened, low plasticity when cold hardened, good corrosion resistance, good weldability, poor machinability.

The Product Features of 3A21 Aluminum Sheet Plate

  • 3A21 aluminum plate has high fatigue strength and shear strength, and high elongation.
  • 3A21 aluminum plate has excellent corrosion resistance and can adapt to humid environment.
  • The surface of the 3A21 aluminum plate is regular, without bumps, bright spots, scratches and other defects.
  • 3A21 aluminum plate has strong corrosion resistance and strong stress corrosion cracking ability.

The Application of 3A21 Aluminum Sheet Plate

3A21 aluminum alloy is mainly used for low-load parts that require high plasticity and good weldability and work in liquid or gas media, such as radiators, fuel tanks, gasoline or lubricating oil conduits, various liquid containers and other small load parts made by deep drawing.
