Constantan Wire Definition 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, or enamelled wire with any insulation and self-bonding
enamel. Furthermore, litz wire made of enamelled copper nickel
alloy wire are available.
Features
1. Higher resistance than copper
2. High tensile strength
3. Good bending proof performance
Application
1. Heating applications
2. Resistance wire
3. Applications with high mechanical requirements
4. Others
