Bayani: Ni327 lantarki ne mai tushen nickel wanda ke da ƙarancin sinadarin sodium. Yi amfani da DCEP (electrode na yanzu kai tsaye).tabbatacce). Karfe da aka ajiye yana da kyakkyawan juriya ga tsagewa saboda walda tana ɗauke da wani adadin abubuwan haɗin gwiwa kamar molybdenum da niobium.
Amfani: Ana amfani da shi don walda gami da nickel waɗanda ke buƙatar juriyar zafi da juriyar tsatsa, kuma ana iya amfani da shi don walda da kuma shimfida wasu ƙarfe masu wahalar walda da ƙarfe daban-daban.
