General Description
Due to has high tensile strength and increased resistivity values, copper nickel alloy wires are 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 enamelled wire with any insulation and self-bonding enamel. Furthermore, litz wire made of enamelled copper nickel alloy wire are available.
