I-CuNi2 resistance alloy luhlobo lwe-copper nickel binary alloy. Inomlinganiselo wobushushu obuphantsi wokumelana nobushushu obuphezulu bokusebenza ngama-250°C. Le alloy isetyenziswa ikakhulu ukwenza i-low-voltage breaker circuit, ingubo yombane yobushushu obuphantsi, i-thermal cutout kunye nezinye izixhobo zombane eziphantsi kombane. Kwaye ikwasetyenziselwa ukwenza ukufudumezaintambongengubo yombane yasekhaya.
