EN AW-1200
3.0205Commercially pure aluminum (99.0% min Al) — the European variant of 1100. Slightly different Si/Fe impurity limits. Same excellent corrosion resistance, conductivity, and formability. Used for heat exchanger fins, foil, chemical equipment, and general sheet applications where high conductivity and corrosion resistance matter more than strength.

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.
