EN AW-6063 vs EN AW-6082: Same 6xxx family — 6063 for surface, 6082 for strength
EN AW-6063 vs EN AW-6082
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-6063
3.3206
The most common extrusion alloy worldwide. Excellent surface finish, good corrosion resistance, and exceptional extrudability. The standard choice for architectural profiles (window frames, curtain walls, railings), heat sinks, and electrical enclosures.
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).
