5083 aluminum alloy is a high-magnesium alloy with good strength among non-heat-treatable alloys, as well as excellent corrosion resistance and machinability.

Chemical Composition: Al (Aluminum): Balance; Si (Silicon): ≤0.40; Cu (Copper): ≤0.10; Mg (Magnesium): 4.0～4.9; Zn (Zinc): ≤0.25; Mn (Manganese): 0.40～1.0; Ti (Titanium): ≤0.15; Cr (Chromium): 0.05～0.25; Fe (Iron): 0.000～0.400

The primary alloying element in the 5083 alloy is magnesium, which provides excellent corrosion resistance, good weldability, and moderate strength. Its superior corrosion resistance makes the 5083 alloy widely used in marine applications such as ships, as well as in automotive and aircraft welded components, subway and light rail systems, pressure vessels requiring strict fire protection (e.g., liquid tankers, refrigerated trucks, refrigerated containers), refrigeration equipment, television towers, drilling equipment, transportation equipment, missile parts, armor, and more.
