EN AW-6061 vs EN AW-6082
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-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.
