Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-6061
3.3211
The most widely used aluminium alloy in North America. Good balance of strength, corrosion resistance, and machinability. Heat treatable (T6). Used for structural components, automotive parts, marine fittings, bicycle frames, and general engineering. Being replaced by 6082 in European applications.
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.
