EN AW-5083 vs EN AW-7050
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-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.
