5083 aluminum alloy is a high-magnesium alloy with good strength, corrosion resistance and machinability among non-heat-treatable alloys. The surface is beautiful after anodizing. Arc welding performance is good. The main alloying element in 5083 alloy is magnesium, which has good corrosion resistance and weldability, as well as medium strength. Excellent corrosion resistance makes 5083 alloy widely used in marine applications such as ships, automobiles, aircraft welding parts, subway light rail, pressure vessels that require strict fire protection (such as liquid tank cars, refrigerated vehicles, refrigerated containers), refrigeration devices, TV towers, Drilling equipment, transportation equipment, missile parts, armor, etc.
