Hana ʻia ka Copper Nickel Alloy i ke keleawe a me ka nickel. Hiki ke hoʻoheheʻe ʻia ke keleawe a me ka nickel me ka nui o ka pakeneka. ʻO ka maʻamau, ʻoi aku ka kiʻekiʻe o ka resistivity o CuNi alloy inā ʻoi aku ka nui o ka Nickel ma mua o ka maʻiʻo Copper. Mai CuNi6 a CuNi44, ka resistivity mai 0.1μΩm a 0.49μΩm. E kōkua ia i ka hana ʻana o ka resistor i ke koho ʻana i ka uea alloy kūpono loa.
