Engineering Summary
5083 (EN AW-5083) is the highest-strength non-heat-treatable Al-Mg alloy (4.5% Mg, 0.7% Mn). Highly regarded for exceptional performance in extreme environments, it offers outstanding resistance to seawater, excellent cryogenic toughness, and high as-welded joint efficiency in heavy plate structures.
