EN AW-6082 vs EN AW-6061
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-6082
3.2315
High-strength structural aluminium alloy in the Al-Mg-Si family. One of the strongest 6xxx series alloys due to manganese addition. Replaced 6061 in many European applications. Used for trusses, bridges, cranes, transport, scaffolding, and marine applications. Heat treatable (T6/T651).
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.
