Constantan Physical Properties

Copper nickel alloy constantan wire, ine yakaderera electric resistance, yakanaka inodzivirira kupisa uye inodzivirira ngura, iri nyore kugadzikiswa uye inotungamira welded. Iyo inoshandiswa kugadzira iyo yakakosha zvikamu mu thermal overload relay, yakaderera kupikisa thermal circuit breaker, uye midziyo yemagetsi. Ichowo chinhu chakakosha chemagetsi ekupisa tambo. Zvakafanana ne's type cupronickel.
