EN AW-6082
3.2315High-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
3.3547The 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-7075
3.4365The classic high-strength aerospace aluminium alloy. Al-Zn-Mg-Cu composition provides the highest strength of all common aluminium alloys in T6 temper. Poor weldability and limited corrosion resistance. Used for aircraft structures, M16 rifle receivers, rock climbing gear, and precision mold plates.
