FeCrAl qotishmasi 0cr21al6Nb spiral elektr hiln isitish batareyasi isitish elementi

0Cr21Al6Nb1350 ° C (2550 ° F) gacha bo'lgan haroratlarda foydalanish uchun temir-xrom-alyuminiy qotishmasi (FeCrAl qotishmasi). Yuqori qarshilik, past haroratli elektr qarshilik koeffitsienti, yuqori ish harorati, yuqori haroratda yaxshi oksidlanish qarshiligi xususiyatlariga ega qotishma. U kanthal A1, Alloy875, Resistohm 145, Aluchrom0, Alchrome875, MWS-875, Stablohm875 ga teng bo'lishi mumkin.

U sanoat elektr pechlari, maishiy elektr jihozlari va uzoq infraqizil nurlanish qurilmalarida keng qo'llaniladi.
Panelli isitgichlar, infraqizil isitgichlar, isitish plitalari, kartrijli isitgichlar, saqlash isitgichlari, pishirish plitalari uchun keramik isitgichlar, pech elementlari, radiatorlar, kosmik isitish uchun kvarts trubkali isitgichlar, tushdi mashinasi, tushdi mashinasi pechlari, sanoat infraqizil quritgichlar, qolipli keramika bobinlari keramik plitalar va boshqalar bilan pishirish plitalari uchun tolalar.
