ERNiCu-7 Nickle-Copper Alloy Welding Wire
ERNiCu-7 Nickle-Copper Alloy Welding Wire Application
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. This Nickle-Copper alloy wire has the similar high strength performance as Monel 400. And it has a good resistance to sea water and reducibility acid.
It is also used for surfacing of steel. Submerged Arc Flux is used with the submerged-arc process. The reaction of titanium with carbon maintains a low level of free carbon and enables the filler metal to be used with Nickel 201. The weld metal has good corrosion resistance, particularly in alkalies.
