EN AW-5083 vs EN AW-6061
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-6061
3.3211
THE US structural aluminum alloy — AlMg1SiCu. Good strength (UTS 290 T6), excellent corrosion resistance, and good weldability. THE default choice in North America for structural and machined parts. Cu addition gives slightly better strength than 6082 in some tempers but slightly worse corrosion. Used for structural frames, bicycle frames, aircraft fittings, marine hardware, and general machined components.
