Aws A5.14 Nickel Alloy Ernicu-7 MIG Welding Wire TIG Welding Rod for Monel 400 Welding

Short 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.

    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.
