Description

Copper Nickel (CuNi) alloys are medium to low resistance materials typically used in applications with maximum operating temperatures up to 600°C (1,110°F).


With low temperature coefficients of electrical resistance, resistance, and thus performance, is consistent regardless of
temperature. Copper Nickel alloys mechanically boast good ductility, are easily soldered and welded, as well as have outstanding corrosion resistance. These alloys are typically used in high current applications requiring a high level of precision.
Constantan Wire 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 wire 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 T thermocouple with OFHC Copper the positive; type T thermocouples are used at cryogenic temperatures.

Copper Nickel Resistance Alloys

Copper Nickel (CuNi) alloys are medium to low resistance materials typically used in applications with maximum operating temperatures up to 400°C (750°F).

With low temperature coefficients of electrical resistance, resistance, and thus performance, is consistent regardless of temperature. Copper Nickel alloys mechanically boast good ductility, are easily soldered and welded, as well as have outstanding corrosion resistance. These alloys are typically used in high current applications requiring a high level of precision.

Resistance heating wire and resistance wire,Common Name:CuNi44,NC50.

NC050 is a copper-nickel alloy (Cu56Ni44 alloy) with low resistivity for use at temperatures up to 400°C.

The ductility of copper-nickel alloy is very good, so it can be used in shipbuilding and petrochemical industry. Some electrical appliances and meters also use the ductility of copper-nickel alloys to manufacture parts. Copper-nickel alloys are mostly used in industrial production. Some valves and some precision resistance parts will be made of copper-nickel alloys.
