Aluminum alloy 5083 is industrial pure aluminum, which has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but its strength is low, heat treatment can not strengthen, and its machinability is poor.
Detailed introduction
About 5083 Aluminium
5083 belongs to Al Mg alloy, which is widely used, especially in construction industry. Good corrosion resistance, good weldability, good 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 fuel tank, oil pipe, sheet metal parts of traffic vehicles and ships, instruments, street lamp bracket and rivets, hardware products, electrical appliance shell, etc.It is a high magnesium alloy with good strength, corrosion resistance and machinability.

Applications for 5083 Aluminium
5083 aluminum alloy is a high magnesium alloy, which has good strength, corrosion resistance and machinability in non heat treatment alloy. The surface is beautiful after anodizing. The performance of arc welding is good. The main alloying element in 5083 alloy is magnesium, which has good corrosion resistance, weldability and medium strength. Due to its excellent corrosion resistance, 5083 alloy is widely used in marine applications, such as ships, automobiles, aircraft welding parts, subway light rail, pressure vessels (such as liquid tank cars, refrigerated vehicles, refrigerated containers), refrigeration devices, television towers, drilling equipment, transportation equipment, missile parts, armor, etc.
Characteristic for 5083 Aluminium
Al Mg alloy is one of the most widely used antirust aluminum, which has high strength, especially fatigue resistance: 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 that require high plasticity and good weldability and work in liquid or gas medium, such as oil tank, gasoline or lubricating oil conduit, various liquid containers and other low load parts made by deep drawing: wire rod is used for rivets.
