ESAB ER5356 Aluminium Welding Wire 1.2 mm, 7 kg Spool — BOLTON SKU 64809.
About the ESAB ER5356 Aluminium Welding Wire 1.2 mm
ESAB ER5356 Aluminium Welding Wire 1.2 mm is a solid aluminium-magnesium MIG welding wire classified to AWS A5.10 ER5356, supplied on a 7 kg spool. The ER5356 classification contains nominally 5% magnesium (4.5–5.5% per the classification chemistry) with a small chromium addition that refines the weld grain structure. It is the general-purpose filler for welding 5xxx-series aluminium-magnesium alloys and is also used on many 6xxx-series structural extrusions. The magnesium content gives good as-welded strength and forms a stable oxide film that resists seawater and chloride attack, which is why ER5356 is widely selected for marine and outdoor aluminium structures. ESAB manufactures its filler metals under certified quality-control programmes to the AWS classification. BOLTON supplies this consumable against request for quotation; state spool quantities and any batch certification requirements in your RFQ.

Typical applications
ER5356 in 1.2 mm diameter is used for MIG welding aluminium plate, extrusions and fabrications in 5xxx and compatible 6xxx alloys — frames, tanks, enclosures and structures exposed to coastal or marine atmospheres. The chloride resistance of the 5% Mg deposit makes it a standard choice where welds face salt spray or wash-down conditions.
