EN AW-2024 vs EN AW-5356
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-5356
EN AW-5356
THE 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.
