EN AC-AlMg3
EN AC-51100Magnesium-alloyed aluminum casting alloy with excellent corrosion resistance, particularly in marine and chemical environments. No silicon addition — relies on Mg 2.5-3.5% for solid solution strengthening. Good weldability and anodizing response. Lower castability than AlSi alloys due to absence of Si. Used for marine fittings, chemical process equipment, food industry components, and architectural castings requiring superior corrosion resistance and anodic finish.

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.
