O le CuNi2 resistance alloy o se ituaiga copper nickel binary alloy. E maualalo le vevela o lona coefficient of resistance ma o lona maualuga o le vevela fa'agaoioia e 250°C. O lenei alloy e fa'aaogaina tele mo le gaosiga o le low voltage circuit breaker, low ventilation electric blanket, thermal cutout ma isi masini eletise maualalo voltage. Ma e fa'aaogaina fo'i mo le gaosiga o le fa'avevela.uaeamo le ie afu eletise mo le fale.
