Electric Resistance Wire Copper Nickel CuNi6 Wire / Copper Nickel Alloy Wire
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 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.
