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
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.
