EN AW-6060 vs EN AW-6063: Near-identical extrusion alloys — 6060 slightly lower strength
EN AW-6060 vs EN AW-6063
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-6060
3.3206
The most widely extruded aluminum alloy in Europe. Lower strength than 6063 but excellent extrudability and surface quality. Used for architectural profiles (window frames, curtain walls, door frames), furniture, heat sinks, and general-purpose extrusions. T6 temper for structural use; T5 for decorative.
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.
