Description
Copper Nickel 70/30 Rod
The weld metal of this wire is developed to match CuNi 70/30 alloys, and is nominally composed of 67% Cu and 30% Ni. This consumable is suitable for both overlays and claddings, provided that a buttering layer is made (usually buttering is done with alloy 400 or pure nickel). Applications include offshore constructions, desalination plants, evaporators, condensers, and other marine and brackish water treatment facilities.
