Constantan Physical Properties

I-copper nickel alloy constantan wire, enokumelana nogesi okuphansi, ukumelana kahle nokushisa kanye nokungagqwali, kulula ukucutshungulwa futhi kushiselwe umthofu.Isetshenziselwa ukwenza izingxenye ezibalulekile ku-thermal overload relay, i-thermal resistance circuit breaker, nezinto zikagesi.Kubuye kube yinto ebalulekile yekhebula lokushisa likagesi.Kuyafana nohlobo lwe-curonickel.

Izici ezibonakalayo ze-constantan yilezi:
