Isku-darka Ni-Cr
Daawada Ni-Cr elektromerka waxay leedahay awood heerkulkeedu sareeyo. Waxay leedahay adkaansho wanaagsan oo si fudud uma beddesho. Qaab dhismeedkeeda hadhuudhku si fudud looma beddelo. Balaastiigga ayaa ka fiican alloysyada Fe-Cr-Al. No burburin ka dib qaboojinta heerkulka sare, nolosha adeegga dheer, ay fududahay in la farsameeyo iyo alxanka, laakiin heerkulka adeegga waa ka hooseeyaa Fe-Cr-Al daawaha. Daawooyinka korantada Ni-Cr waa mid ka mid ah wax soo saarka ugu muhiimsan ee shirkadeena. Dhammaan alaabooyinka kuleylka ee kuleylka ee ay soo saarto shirkadeena waxaa lagu kala soocayaa isku-dhafka isku-dhafan, iska caabin sare, tayo deggan, cabbir sax ah, nolol shaqeyn dheer iyo habsami u socod wanaagsan Macaamiisha ayaa ku dooran kara darajada ku habboon shuruudaha kala duwan.
