5356 wire is not recommended for cast aluminium or high-silicon/high-zinc base alloys, use 4043 or a silicon-based filler for those instead. Weldments should also avoid sustained service temperatures above 65°C where the weld pool magnesium content exceeds 3%, due to stress corrosion cracking susceptibility, standard practice across all AlMg5-type fillers.

EXPLORE THIS PRODUCT
RONWELD Pulse Ready 5356 is a premium aluminium-magnesium MIG welding wire engineered for consistent, spatter-free performance on pulse MIG power sources. With a nominal 5% magnesium content, it delivers the strength, ductility, and corrosion resistance fabricators rely on for structural, marine, and transport applications, while its precision layer-winding and tight diameter tolerance keep feeding smooth through push-pull guns and standard drive rolls alike.
Formulated to AWS A5.10 / ISO 18273 ER5356 (AlMg5Cr(A)) specification, this wire is the go-to general-purpose filler for 5xxx series aluminium alloys, and is also the preferred choice for welding 6061 and other 6xxx series aluminium where anodised colour-match after welding matters.
Pulse-optimised for clean arc starts. Consistent chemistry and surface finish reduce burnback and bird-nesting on synergic pulse MIG programs.
5% magnesium alloy (AlMg5). Provides higher tensile strength than 4043 wire, along with excellent resistance to saltwater and marine atmosphere corrosion.
Precision layer-wound spools. Smooth, tangle-free unwinding for both semi-automatic and robotic/automated welding cells.
Anodise-matched welds. Deposits weld white and blends closely with 5xxx base metal after anodising, ideal for visible or decorative structural work.
Broad alloy compatibility. Suitable for 5052, 5083, 5086, 5454, 5456, and for structural welds on 6061 and 6063 where higher strength is required.
