EN AW-2024 vs EN AW-1050A
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-2024
3.1355
Classic high-strength aerospace aluminium alloy (Al-Cu-Mg). Excellent fatigue resistance — the standard choice for aircraft fuselage skins and wing tension members. Poor corrosion resistance and weldability. Often supplied with Alclad cladding for corrosion protection. In use since 1931.
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.
