Description
AA 5083 is a high-strength aluminum-magnesium alloy (4.0–4.9% Mg) widely used in marine and cryogenic applications due to its exceptional corrosion resistance in seawater and retention of toughness at very low temperatures. It is non-heat-treatable but achieves moderate-to-high strength through solid solution strengthening and work hardening. Primary applications include shipbuilding, liquefied natural gas (LNG) tanks, railway vehicles, and structural plate applications.
