Product Datasheet: ERCuNi MIG Wire, TIG Rods, & SAW Wires (MONEL® Alloys 450)
Product Overview:
ERCuNi is a copper-nickel alloy wire used for welding and repair of 70/30 and 90/10 copper-nickel alloys. This wire is notable for its excellent resistance to corrosion, especially in marine and saltwater environments. It is also used in applications requiring high thermal and electrical conductivity.
