Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-6061
3.3211
The most widely used aluminium alloy in North America. Good balance of strength, corrosion resistance, and machinability. Heat treatable (T6). Used for structural components, automotive parts, marine fittings, bicycle frames, and general engineering. Being replaced by 6082 in European applications.
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.
