EN AW-6063 vs EN AW-1050A
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-1050A
3.0255
Commercially pure aluminum (99.5% Al minimum). Excellent corrosion resistance, highest thermal and electrical conductivity among Al alloys, and outstanding formability. Low strength (UTS ~100 MPa annealed) limits structural use. Non-heat-treatable — strengthened only by cold work (H14/H24 tempers). Used for chemical processing equipment, food packaging foil, reflectors, heat exchangers, electrical busbars, capacitor foils, and architectural cladding/roofing. The baseline aluminum for conductivity applications.
