EN AW-2024 vs EN AW-3004
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-3004
EN AW-3004
Al-Mn-Mg alloy — THE beverage can body material. Mn 1.0-1.5% + Mg 0.8-1.3% give moderate strength (UTS 240-280 H19) with excellent formability for deep drawing and ironing. ~200 billion cans/year worldwide. Also used for roofing sheet, color-coated panels, and storage tanks. Stronger than 3003 due to Mg addition.
