Constantan Physical Properties

I-copper nickel alloy constantan wire, enokumelana nombane okuphantsi, ukumelana nobushushu kunye nokumelana nomhlwa, kulula ukuqhutyelwa phambili 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:
