EN AW-5083 vs EN AW-6061
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-6061
3.3211
The most widely used aluminium alloy in North America. Good balance of strength, corrosion resistance, and machinability. Heat treatable (T6). Used for structural components, automotive parts, marine fittings, bicycle frames, and general engineering. Being replaced by 6082 in European applications.
