1. FM60 Oxford Alloy 60 ERNiCu-7 TIG welding rod
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.

APPLICATIONS
ERNiCu-7 can be used for dissimilar welding applications using various nickel-copper alloys to nickel 200 and to copper-nickel alloys.
ERNiCu-7 is used for gas-tungsten-arc, gas-metal-arc, and submerged-arc welding of Monel alloy 400 and K-500.
ERNiCu-7 is widely used in marine applications because of its good resistance to the corrosive effects of seawater and brackish waters.
