FecralUpinzani wa juu na aloi ya kupokanzwa umeme
Upinzani wa fecral na aloi ya kupokanzwa na sifa za upinzani mkubwa, mgawo wa joto la chini la upinzani wa umeme, joto la juu la kufanya kazi, upinzani mzuri wa kutu chini ya joto la juu, na bei ya chini.
Inatumika sana katika tanuru ya umeme ya viwandani, vifaa vya umeme vya kaya na kifaa cha ray cha mbali.
