FCHW-1 pechini qo'llash uchun 0Cr25Al5 isitish qotishma lentasi
NiCr qotishmasiga qaraganda yuqori qarshilik va xizmat ko'rsatish haroratiga ega Fe-Cr-Al qotishmasi, shuningdek, pastroq narxga ega.
Ilovalar:Temir-xrom-alyuminiy elektr esistorlari maishiy texnika va sanoat pechlarida elektr isitish elementlarini, yog 'radiatorlarini, ionlash mashinalarini, natriy isitgichlarni, plastilin qoliplarini, lehim dazmollarini, metall qoplamali quvurli elementlarni va kartrij elementlarini ishlab chiqarishda keng qo'llaniladi.
