5083 aluminum alloy is a high magnesium alloy with good strength, corrosion resistance, and machinability among non heat treatable alloys. The surface is aesthetically pleasing after anodizing treatment. The arc welding performance is good. The main alloying element in 5083 alloy is magnesium, which has good corrosion resistance, weldability, and moderate strength. The excellent corrosion resistance of 5083 alloy makes it widely used in maritime applications such as ships, as well as welding parts for automobiles, airplanes, subways, light rails, pressure vessels that require strict fire prevention (such as liquid tankers, refrigerated trucks, refrigerated containers), refrigeration devices, TV towers, drilling equipment, transportation equipment, missile parts, armor, etc。
