EN AW-1050A vs EN AW-2024
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-1050A
3.0255
Commercially pure aluminium (99.5% min Al). Excellent corrosion resistance, thermal and electrical conductivity. Very soft and easily formed. Used for chemical plant equipment, food industry, reflectors, heat exchangers, electrical conductors, and decorative trim.
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.
