As a big manufacturer and exporter in China on the line of electric resistance alloy, we can supply all kinds of
electric resistance alloy wire and strips (resistance steel wire and strips),
Material: CuNi1, CuNi2, CuNi6, CuNi8, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi44
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,
