Applications
Typical applications for CuNi44 alloy include temperature stable potentiometers, industrial rheostats, electric motor starter resistances, volume control devices, to name a few.
For thermocouple applications, it is coupled with copper, iron, and Ni-Cr to form Type T, Type J, and Type E thermocouples, respectively.
