EN AW-6061 vs EN AW-6082: Same 6xxx family — 6082 is the stronger European alternative
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
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).
