EN AW-5083 vs EN AW-2024
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-5083
3.3547
The highest-strength non-heat-treatable aluminium alloy. Excellent corrosion resistance (especially seawater), good weldability. Standard alloy for shipbuilding, offshore, pressure vessels, cryogenic applications, and armour plate. Not for continuous service above 65°C under stress (SCC risk).
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.
