3003 aluminum plate and 3004 aluminum plate series are al Mn alloys, which are the most widely used antirust aluminum. The strength of this alloy 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: high plasticity in annealing state, good plasticity in semi cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability, and poor machinability. It is mainly used for low load parts that require high plasticity and good weldability and work in liquid or gas media, such as mailbox, gasoline or lubricating oil conduit, various liquid containers and other low load parts made by deep drawing: wire rod is used to make rivets.
3003 aluminum sheet has good formability, weldability and corrosion resistance. 3003 aluminum plate is commonly used in ships, ships, vehicle materials, automobile and aircraft plate weldments, pressure vessels that need strict fire protection, refrigeration devices, television towers, drilling equipment, transportation equipment, missile components, armor, etc.
3004 aluminum plate has higher strength than 3003 aluminum plate, excellent formability and good corrosion resistance. Parts with higher strength than 3003 aluminum plate are required.
3004 aluminum strip is mainly used in the production and storage devices of chemical products, sheet metal processing parts, building materials, building baffles, cable ducts, sewers, various lamp parts, beverage cans, wave plates, building materials, colored aluminum plates, and electric lamp heads.
