Constantan Resistance Wire Copper Nickel Alloy CuNi44 CuNi23,
Nickel Copper Wire Details: Copper nickel alloy has low electric resistance,good heat-resistant
and corrosion-resistant,easy to be processed and lead welded.
It isused to make the key components in the thermal overload
relay,low resistance thermal circuit breaker, and the electrical
appliances.
It is also an important material for electrical heating cable. | Nickel | 23 | Manganese | 0.5 | | Copper | Bal. | | |

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.
