ERCuNi Copper-Nickel Alloy Welding Wire

ERCuNi Copper-Nickel Alloy Welding Wire Application

ERCuNi Copper-Nickel Alloy Welding Wire is especially good for seawater corrosion resistance. It is particularly suitable for the welding and hard facing of copper-nickel such as machinery, desalting of seawater, ship-building, oil refinery, and food processing industries. This copper-nickel alloy wire is also suitable for welding of nonferrous alloys, dissimilar steel materials.

This alloy can be used for dissimilar welding applications welding various copper-nickel alloys to nickel alloys and various other copper-nickel alloys. ERCuNi is occasionally used for overlay on carbon steel, but can only be used after applying a layer of ERNi-1 first.
