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-2024
EN AW-2024
THE aerospace aluminum alloy — Al-Cu-Mg, introduced by Alcoa in 1931 as "Dural". Excellent fatigue resistance and damage tolerance. T3: UTS 400-470 MPa, good natural aging. Not weldable, poor corrosion resistance (often Alclad). Used for aircraft fuselage skins, wing skins, structural members under tension, ribs, and frames. Also: hydraulic valve bodies, gears, computer parts.
