I-copper nickel alloy, enokumelana nombane okuphantsi, ukumelana nobushushu kunye nokumelana nokugqwala, kulula ukusetyenzwa kwaye kufakwe i-welded. 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.Ukwakhiwa kwe-Nickel, kokukhona kuya kuba mhlophe umphezulu wesilivere.
