Constantan Physical Properties

I-copper nickel alloy constantan wire, enokumelana nombane okuphantsi, ukumelana nobushushu kunye nokumelana nomhlwa, kulula ukusetyenzwa kunye nokudityaniswa kwelothe.Isetyenziselwa ukwenza amacandelo aphambili kwi-thermal overload relay, i-low resistant thermal circuit breaker, kunye nezixhobo zombane.Kwakhona yinto ebalulekileyo kwikhebula lokufudumeza kombane.Iyafana nohlobo lwe cupronickel.

Iimpawu ezibonakalayo ze-constantan zezi:
