EN AW-5356
EN AW-5356THE magnesium-aluminum welding filler wire — Mg 4.5-5.5% + Cr 0.05-0.20%. Together with 4043, accounts for the vast majority of all Al welding wire sold. ER5356/AlMg5Cr(A). Better color match after anodizing than 4043 (no dark spots). Higher weld strength than 4043. Used for MIG/TIG welding of 5xxx and 6xxx base alloys. THE filler for marine, structural, and anodized applications.

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.
