EN AW-7050 vs EN AW-6060
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-7050
3.4144
High-strength aerospace aluminium developed by Alcoa for thick-plate applications. Zr addition (instead of Cr) reduces quench sensitivity for superior properties in thick sections. T7451 temper gives excellent SCC resistance + fracture toughness. Used for fuselage frames, bulkheads, wing spars, and thick structural aerospace components.
EN AW-6060
3.3206
The most extruded aluminum alloy in Europe — optimized for complex thin-walled extrusion profiles. Lower Mg+Si content than 6063/6082 provides excellent extrudability at moderate strength (UTS ~215 MPa T6). Good corrosion resistance, anodizability (decorative quality), and weldability. The default material for window/door frames, curtain wall mullions, railing systems, heat sinks, LED lighting profiles, and general architectural extrusions. EN AW-6063 is the closest ASTM equivalent.
