CuNi44 Constantan Resistance Copper Nickel Alloy Strip Resistance Tape

Constantan
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 manganins.
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 T thermocouple with OFHC Copper the positive; type T thermocouples are used at cryogenic temperatures.

Application:
CuNi44 is a copper-nickel alloy that contains specific minor amounts of additional elements to achieve precise values for the temperature coefficient of resistivity. Careful control of melting and conversion practices results in a very low level of pinholes at
ultra-thin thicknesses. The alloy is used extensively for foil resistors and strain gauges.
