Weld Star ER 5556 (AlMg5Mn) Wire [7kg Spool]

Elevate your aluminium fabrication with Weld Star ER 5556, a premium high magnesium solid wire engineered for demanding structural and marine applications. This AlMg5Mn alloy is specifically designed to provide higher as welded tensile strength compared to the more common ER 5356, making it the professional choice for high stress joints.

The addition of Manganese (Mn) and a precisely controlled Magnesium (Mg) content ensures excellent resistance to stress corrosion cracking and superior performance in saltwater environments. Supplied on a 7kg spool, this wire is precision cleaned and layer wound to ensure the consistent, snag free feeding required for high quality aluminium GMAW. Whether you are building high speed ferries, naval vessels, or heavy duty storage tanks, Weld Star ER 5556 delivers the metallurgical integrity required for certified marine and structural work.
