EN AW-2024 vs EN AW-6082
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-2024
3.1355
Classic 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.
EN AW-6082
3.2315
THE European structural aluminum alloy — AlSi1MgMn. Highest strength in the 6xxx series (UTS 310 T6). Excellent machinability, good weldability (but HAZ softening), and good corrosion resistance. THE default choice for structural aluminum in Europe — equivalent to what 6061 is in the US. Used for bridges, cranes, transport structures, offshore, and machined components.
