EN AW-5083 vs EN AW-5356
Side-by-side chemical composition and mechanical property comparison.
Overview
EN AW-5083
3.3547
The 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-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.
