Where can I buy Indalco aluminum welding wire in Asia?

Mastership is the sole authorized distributor of Canadian Indalco aluminum welding consumables in Asia, headquartered in Chiayi, Taiwan. We stock the full range — ER4043, ER4047, ER5183, ER5356 and ER5554 — and provide free sample testing and technical consultation, with export service across Asia.

ER5356 or ER4043 — which should I choose?

ER5356 offers higher strength and better corrosion resistance — the usual choice for marine work, structural parts and 5xxx-series base metals. ER4043 flows better and is less crack-sensitive — suited to castings and general welding. Tell us your base alloy and application and we will recommend a grade.

Which international certifications do the products carry?

Indalco consumables hold classification society type approvals from ABS, DNV, LR, BV and CCS, plus CWB (Canadian Welding Bureau) certification and manufacture under ISO 9001. The grades themselves conform to the AWS A5.10 specification, which is a standard rather than a certifying body. Together these meet the demands of shipbuilding, offshore, rail and aerospace industries. See Certifications.

What is the difference between TGM and INDALCO?

INDALCO is imported from Canada — the first choice for high-end, high-requirement applications. TGM is Mastership’s value brand: dependable quality across a full range of sizes at a competitive price. Both come with Mastership’s technical support and sample service.
