General Description

ERNiCu-7 is used for GMAW, GTAW, and SAW welding of Monel 400 and Monel K500. It is also suitable for the welding of Monel 400 to copper-nickel alloys and carbon steels.

Weld metal formed by ERNiCu-7 has the similar high strength performance as Monel 400. And it has a good resistance to sea water and reducibility acid.
