n. a copper-nickel alloy composed of approximately 55 per cent copper and 45 per cent nickel, with high electrical resistance and a low temperature coefficient; it is used as resistance wire and in thermocouples. It has a resistance factor of 44.1 x 10-6 ohm-cm at 0 C, in comparison to the value 1.71 x 10-6 ohm-cm for pure copper and 7.8 x 10-6 ohm-cm for pure nickel. It is similar to the alloy Eureka, which has a = 47 x 10-6 ohm-cm. Handbook of Ch. 61.
