CuNi10 Copper-Nickel Welding Wire APPLICATION

Due to high tensile strength and increased resistivity values, CuNi10 is the first choice for applications as resistance wires. With the different nickel amount in this product range, the characteristics of the wire can be chosen according to your requirements. Copper-nickel alloy wires are available as bare wire, or enameled wire with any insulation and self-bonding enamel. Furthermore, Litz wire made of enameled copper-nickel alloy wire are available.

Copper Nickle Welding wire is especially good for seawater corrosion resistance. Particularly suitable for the welding and hard facing copper-nickel alloys such as machinery, desalting of seawater, ship-building, oil refinery, and food processing industries.

This alloy presents the particularity to be very malleable, to have good resistance to corrosion until temperatures of 400°C, and good solderability. Ideal application areas are all types of resistances used at low temperatures.
