CuNi2 resistance alloy imhando yemhangura nickel binary alloy. Iyo ine yakaderera tembiricha coefficient yekupikisa uye yakanyanya tembiricha yekushanda i250 ° C. Iyi alloy inonyanya kushandiswa kugadzira yakaderera voltage circuit breaker, yakadzika tembiricha yemagetsi gumbeze, thermal cutout uye zvimwe zvakaderera magetsi magetsi. Uye zvakare inoshandiswa kugadzira kupisacableyegumbeze remagetsi repamba.
