EN AW-2017A
3.1325Heat-treatable Al-Cu-Mg alloy (Duralumin family). Higher strength than 6xxx series in T4 condition (UTS ~430 MPa) with excellent machinability. Not suitable for welding due to Cu content. Limited corrosion resistance — usually anodized or clad. Standard material for turned parts, screw machine products, fittings and structural components requiring high strength. One of the original aerospace aluminum alloys.

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-2024
3.1355Classic high-strength aerospace aluminium alloy (Al-Cu-Mg). Excellent fatigue resistance — the standard choice for aircraft fuselage skins and wing tension members. Poor corrosion resistance and weldability. Often supplied with Alclad cladding for corrosion protection. In use since 1931.
