EN AW-5083 vs EN AW-6082
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-6082
3.2315
THE European structural aluminum alloy — AlSi1MgMn. Highest strength in the 6xxx series (UTS 310 T6). Excellent machinability, good weldability (but HAZ softening), and good corrosion resistance. THE default choice for structural aluminum in Europe — equivalent to what 6061 is in the US. Used for bridges, cranes, transport structures, offshore, and machined components.
