EN AW-7050 vs EN AW-2024
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-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.
