EN AW-5083 vs EN AW-5182: Both high-Mg 5xxx alloys — different application domains
EN AW-5083 vs EN AW-5182
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-5083
3.3547
The highest-strength non-heat-treatable aluminium alloy. Excellent corrosion resistance (especially seawater), good weldability. Standard alloy for shipbuilding, offshore, pressure vessels, cryogenic applications, and armour plate. Not for continuous service above 65°C under stress (SCC risk).
EN AW-5182
3.3519
One of the strongest non-heat-treatable Al-Mg alloys. 4.5% Mg + 0.35% Mn. THE standard alloy for beverage can lids/pull tabs (H48 temper). Also used for automotive body panels (hoods, doors), fuel tanks, and marine components. Excellent corrosion resistance and formability.
