Copper nickel alloy ine yakaderera electric resistance, yakanaka isingadziviriri uye isingadzivirirwe nekuora, iri nyore kugadzikiswa uye kutungamirira welded. Iyo inoshandiswa kugadzira iyo yakakosha zvikamu mu thermal overload relay, yakaderera kupikisa thermalcircuit breaker, uye midziyo yemagetsi. Ichowo chinhu chakakosha chemagetsi ekupisa tambo.
