5083 aluminium alloy belongs to Al-Mg system welding, which is widely used, especially in the construction industry. It is a promising alloy with good corrosion resistance, excellent welding performance, good cold workability and medium strength. The main alloying element of 5083 aluminum is magnesium which has good forming and processing performance, corrosion resistance, weldability and medium strength. It is used in manufacturing aircraft fuel tank, fuel pipe, sheet metal parts of traffic vehicles and ships, meters, street lamp brackets and rivets, hardware products, electrical appliances, etc.
5083 Al-Mg aluminium alloy is a kind of widely used rust-proof aluminium, which has high strength, especially fatigue strength; high plasticity in corrosion,it can not be strengthened by heat treatment, good in Semi-cold work hardening, cold work hardening is low plasticity, 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 media, such as mailbox, gasoline or lubricant conduit, various liquid containers and other low-load parts made by deep drawing.
