Application
ENiCu-7 (NA190) is used for welding materials of nickel-copper alloys to themselves, such as ASTM B127, B163, B164, and B165. Can be used for overlay of clad steels where nickel-copper surfacing is required. Dissimilar welding applications include joining Nickel 200 and copper-nickel alloys.
