Zvivakwa zveConstantan

Waya yesimbi ye constantan ine nickel alloy, ine simba shoma remagetsi, inodzivirira kupisa uye inodzivirira ngura, iri nyore kugadziriswa uye inosungirirwa ne lead. Inoshandiswa kugadzira zvinhu zvakakosha mu thermal overload relay, thermal circuit breaker ine simba shoma, uye midziyo yemagetsi. Ichinhu chakakoshawo chetambo yemagetsi yekudziisa. Yakafanana ne 's type cupronickel.

Hunhu hwemuviri hwe constantan ndehwekuti:
