FeCrAlyuqori qarshilik va elektr isitish qotishmasi

FeCrAl qarshilik va isitish qotishmasi yuqori qarshilik, past haroratli elektr qarshilik koeffitsienti, yuqori ish harorati, yuqori haroratda yaxshi korroziyaga chidamliligi, shuningdek, past narx.

U sanoat elektr pechlarida, maishiy elektr jihozlarida va uzoq infraqizil nurlanish qurilmalarida keng qo'llaniladi.
