Description
ERNiCu-7 has good strength and resists corrosion in many media, including seawater, salts, and reducing acids. And it can be used to overlay over carbon steel, provided a buffer layer of ERNi-1 is used for the first layer. This alloy is not age hardnable and when used to join Monel K-500 has lower strength than the base metal.. It can equivalent to: Oxford Alloy 60  FM 60 , Techalloy 418.

Applications
Dissimilar welding applications include joining alloys to Nickel 200 and copper-nickel alloys. Widely used in marine applications because of its good resistance to the corrosive effects of seawater and brackish waters. Can be used for MIG overlay on steel after a first layer with nickel 208.
