ERNICU-7 (Alloy 60)
Alloy Type: A5.14, NICKEL AND NICKEL ALLOY Bare Electrodes and Welding Rods
ERNiCu7 Nickel Alloy 60 is used for MIG, TIG, and SAW welding of copper alloys. It is used for joining base materials such as UNS number NO4400, NO4405 and NO5500. This alloy can be used for dissimilar welding applications using various nickel-copper alloys to nickel 200 and to copper-nickel alloys. This can be used for MIG overlay on steel after a first layer with nickel 208.
