| Cuprothal 49 is a Copper Nickel alloy, manufactured under close control from electrolytic Copper and pure Nickel. Its high electrical resistance, good ductility and non-corroding properties are very attractive for a variety of applications.In finer sizes its 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. In this case the alloy is identified as Cuprothal 49 TC. Other applications are: temperature stable potentiometers, industrial rheostats and electric motor starter resistances.
