Merit
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.
Applications
Temperature stable potentiometers, industrial rheostats, electric motor starter resistances, volume control devices,etc.
