EN AC-AlSi8Cu3
EN AC-46200General-purpose aluminum sand and gravity die casting alloy with copper addition for improved strength. Si 7.5-9.5% and Cu 2.0-3.5% provide good castability and moderate strength without heat treatment. Used for general-purpose engine components, industrial housings, pump bodies, and medium-duty structural castings where machinability is important. Lower Fe tolerance than EN AC-46000 makes it suitable for sand/gravity casting.

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.
