5A05 aluminum plate is Al-Mg series aluminum alloy, the strength is similar to 5A03, the plasticity is high in annealing state, and the plasticity is medium in semi-cold hardening. The welding performance of 5A05 aluminum plate is good when hydrogen atom welding, spot welding, gas welding and argon arc welding. High corrosion resistance, machinability is poor in annealing state, machinability is good when semi-cold hardening, and anodizing is required when manufacturing rivet.
5A05 aluminum plate is a widely used anti-rust aluminum, with excellent processing properties, corrosion resistance and high strength, suitable for the manufacture of ships, aerospace, railway vehicles, automobiles, construction and other fields of structural parts and components.
3A21 aluminum plate has good corrosion resistance and can adapt to wet environment. In addition, its weldability and machinability are also good. Because of these characteristics, 3A21 aluminum is widely used in the manufacture of various parts and components, such as fuel tanks, pipes, containers, rivets, etc.
In short, 3A21 aluminum sheet is an aluminum alloy material with excellent properties, which is suitable for various processing and manufacturing fields.
