An alloy having an electrical resistance that varies only very slightly with temperature (over a limited range around normal room temperatures). It consists of copper (50–60%) and nickel (40–50%) and is used in resistance wire, thermocouples, etc.

Electronics and Electrical Engineering
An alloy of copper (50–60%) and nickel that has a very low temperature coefficient of resistance and a comparatively high resistance. It is used with copper, silver, etc., to form thermocouples and also for precision wire-wound resistors.
