EN AW-7050 vs EN AW-5083
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-5083
3.3547
The highest-strength non-heat-treatable aluminum alloy. Al-Mg4.5-Mn with outstanding seawater and industrial chemical resistance. Retains exceptional strength after welding (unlike 6xxx/7xxx). ASTM B928 certified for marine service. THE shipbuilding aluminum — also used for rail cars, pressure vessels, cryogenic tanks, truck bodies, and LNG applications. Available O, H111, H116, H321 tempers.
