EN AW-5754 vs EN AW-7050
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-5754
3.3535
Medium-strength non-heat-treatable aluminium alloy with good corrosion resistance and excellent weldability. Lower Mg than 5083 for better formability. The standard alloy for automotive body panels (inner), chemical equipment, and food industry applications.
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.
