I-CuNi2 resistance alloy iwuhlobo lwe-copper nickel alloy kanambambili. Ine-coefficient yokushisa ephansi yokumelana futhi izinga lokushisa layo eliphezulu lokusebenza ngu-250 ° C. Le alloy isetshenziselwa ikakhulukazi ukukhiqiza i-low voltage circuit breaker, i-low-light blanket kagesi, i-thermal cutout kanye namanye amadivaysi kagesi aphansi. Futhi isetshenziselwa ukwenza ukushisaikhebulangengubo kagesi yasekhaya.
