The strength of aluminum sheet 3003 is not high (slightly higher than industrial pure aluminum) and cannot be strengthened by heat treatment. Therefore, cold working methods are used to improve its mechanical properties: it has high plasticity in the annealed state, and the plasticity is good when hardened in semi-cold work. When hardened, the plasticity is low, the corrosion resistance is good, the weldability is good, and the machinability is poor. The strength of aluminum sheet 3004 is higher than that of 3003 aluminum plate, with excellent formability and good corrosion resistance. It requires parts with higher strength than 3003 aluminum plate.
Aluminum sheet 3004 has good formability, weldability and corrosion resistance. 3003 aluminum plates are commonly used in ships, ships, vehicles, automotive welding parts, pressure vessels that require strict fire protection, refrigeration devices, TV towers, drilling equipment, transportation equipment, etc.
3004 aluminum sheet is mainly used in chemical product production and storage devices, thin sheet processed parts, building materials, building baffles, cable pipes, sewers, various lighting components, beverage cans, corrugated boards, building materials, colored aluminum plates, and electric lamp holders.
