Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-6082
3.2315
High-strength structural aluminium alloy in the Al-Mg-Si family. One of the strongest 6xxx series alloys due to manganese addition. Replaced 6061 in many European applications. Used for trusses, bridges, cranes, transport, scaffolding, and marine applications. Heat treatable (T6/T651).
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.
