EN AW-2024 vs EN AW-5052
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-5052
EN AW-5052
General-purpose Al-Mg alloy — Mg 2.2-2.8%. Good balance of formability, corrosion resistance, and moderate strength (UTS 210-260 H32). Non-heat-treatable — strengthened by cold work. THE most widely used 5xxx alloy globally by tonnage. Used for sheet metal work, fuel tanks, marine components, appliances, lighting, and general fabrication. Excellent weldability.
