BrandRescal (France)

CuNi44 offers high electrical resistivity and very low temperature coefficient of resistance (TCR). Due to its low TCR, it finds use in wire-wound precision resistors that can operate up to 400°C (750°F). This alloy is also capable of developing a high and constant electromotive force when coupled with copper. This property allows it to be used for thermocouple, thermocouple extension and compensating leads. It is easily soldered, welded, and offers good corrosion resistance against atmospheric conditions.

MaterialBright Annealed

Cuprothal® 49 is an austenitic copper-nickel alloy (CuNi alloy) for use at temperatures up to 600°C (1110°F). The alloy is characterized by high electrical resistance, high ductility and good corrosion resistance.

In finer sizes the alloy's negligible temperature coefficient of resistance combined with its high resistivity makes it useful for the winding of precision resistors which must not change in resistance over a limited range in temperature. For this purpose the alloy is identified as Cuprothal® 49 TC.

Other typical applications are:

  • Temperature-stable potentiometers
  • Industrial rheostats
  • Electric motor starter resistances.
