Izinhlobonhlobo ezihlukene ze-Copper ephezulu & ne-low Nickel alloys enokumelana okukhethekile okuphezulu noma okuphansi kuyaphawuleka nge-coefficient ephansi yezinga lokushisa lokumelana. Njengoba inokumelana okuphezulu ne-oxidation kanye nokugqwala kwamakhemikhali, lawa ma-alloys asetshenziselwa ukumelana nenxeba lokunemba ngocingo, ama-potentiometer, amadivaysi okulawula ivolumu, ama-rheostats ezimboni ezisindayo ezihehayo kanye nokumelana nemoto kagesi. Izinhlobonhlobo ezihlukene zisetshenziselwa ukushisisa izintambo ezinamazinga okushisa e-conductor aphansi nanjengokushisela kwamashubhu "kuzinto zokushisela zikagesi".Ingxube ye-Copper Manganesekusetshenziswa impahla ejwayelekile yokunemba, i-standard kanye ne-shunt resistors.
