CuNi44 Alloy Flat Wire bright surface with High resistance for electrical elements
Constantan Wire Definition Resistance alloy with moderate resistivity and low temperature coefficent of resistance with a flat resistance/temperature curve over a wider range than the "manganins". Constantan also shows better corrosion resistance than the man ganins. Uses tend to be restricted to ac circuits. Constantan is also the negative element of the type J thermocouple with Iron being the positive; type J thermocouples are used in heat treating applications. Also, it is the negative element of the type Tthermocouple with OFHC Copper the positive; type T thermocouples are used at cryogenic temperatures.

Mechanical Properties
1. CuNi44, also called Constantan, has a very low temperature
coefficient, high electrical resistance, high ductility and
non-corroding properties. It is suitable for use at temperatures up
to 600° C (1110° F). As a very malleable, very ductile alloy, it
has a very good resistance to oxidation.
General DescriptionDue to high tensile strength and increased resistivity values, ELEKTRISOLA 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.
