An alloy of 45 percent nickel and 55 percent copper, used chiefly in electrical instruments because of its constant resistance under variations of temperature.

[From constant.]


(Metallurgy) an alloy of copper (60 per cent) and nickel (40 per cent). It has a high resistivity that does not vary significantly with temperature and is used in resistors and, with copper, in thermocouples
