English → English (gcide) Definition: constantan constantan \constantan\ 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. Note: It has a resistance factor [rho] of 44.1 x 10^-6 ohm-cm at 0[deg] 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 [rho] = 47 x 10^-6 ohm-cm. --Handbook of Ch. 61. [WordNet 1.5 +PJC]
