FeCrAlupinzani wa juu na aloi ya kupokanzwa umeme
Upinzani wa FeCrAl & aloi ya kupokanzwa yenye sifa za upinzani wa juu, mgawo wa joto la chini la upinzani wa umeme, joto la juu la uendeshaji, upinzani mzuri wa kutu chini ya joto la juu, pamoja na bei ya chini.
Inatumika sana katika tanuu ya umeme ya viwandani, vifaa vya umeme vya nyumbani na kifaa cha mionzi ya infrared.
