Aluminium Welding Wire (MIG & TIG)
Aluminium MIG welding wire and TIG filler rods: ER5356 and ER4043, with ER5183 and ER4047 on request. Sold by weight (per kg).
Grades and sizes
ER5356
The most widely used wire for welding 5xxx (AlMg) alloys and the 6xxx series; suitable for anodising after welding. It contains about 5 % magnesium; its welds have higher strength and ductility than those made with ER4043, and after anodising the weld colour is closer to the base metal. It is also suitable for welded structures in marine environments.
ER4043
For welding the 6xxx series and cast aluminium; it gives fluid, crack-resistant welds. It contains about 5 % silicon; its lower melting temperature reduces the tendency to hot cracking and gives a smooth weld appearance. After anodising, the weld turns grey. It is not recommended for welding alloys with a high magnesium content (e.g. 5083).
On request
ER5183 (AlMg4,5Mn0,7(A)) for welding high-strength alloys such as 5083; ER4047 (AlSi12(A)) for welding thin-walled parts and for brazing aluminium. ER5183 gives higher weld strength than ER5356. If you tell us the base material and any post-weld treatment (such as anodising), we can help select the right wire.

Frequently asked questions
ER5356 or ER4043: which should I use?
ER5356 is preferred where high strength and anodising after welding are required; ER4043 is preferred for the 6xxx series and cast aluminium, for good fluidity and crack-resistant welds.
