Composition, Properties and Typical Uses of Aluminum Alloy 5083

The main alloying element in the 5083 alloy is magnesium, which has good corrosion resistance and weldability, as well as moderate strength. Excellent corrosion resistance makes 5083 alloy widely used in marine applications such as ships, as well as automotive, aircraft welding parts, subway light rails, pressure vessels that require strict fire prevention (such as liquid tankers, refrigerated trucks, refrigerated containers), refrigeration equipment, television towers, Drilling equipment, transportation equipment, missile parts, armor, etc.
