EN AW-7050 vs EN AW-5052
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-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.
