5083 is a kind of Al Mg Si alloy, which is widely used, especially in the construction industry. It is the most promising alloy. It has good corrosion resistance, weldability, cold workability and medium strength. The main alloy element of 5083 is magnesium, which has good formability, corrosion resistance, weldability and medium strength. It is used to manufacture aircraft oil tank, oil pipe, sheet metal parts of traffic vehicles and ships, instrument, street lamp bracket and rivet, hardware products, electrical shell, etc.

Al-Mg alloy is the most widely used antirust aluminum, which has high strength, especially fatigue strength: high plasticity and corrosion resistance, can not be strengthened by heat treatment, good plasticity in semi cold work hardening, low plasticity in cold work hardening, good corrosion resistance, good weldability, poor machinability and polishing. It is mainly used for low load parts which require high plasticity and good weldability and work in liquid or gas medium, such as mailbox, gasoline or lubricating oil conduit, various liquid containers and other small load parts made by deep drawing: wire rod is used for rivets.
