ʻO nā mea hao Chrome Aluminum (FeCrAl) nā mea kūʻē kiʻekiʻe i hoʻohana maʻamau i nā noi me nā mahana hana kiʻekiʻe a hiki i 1,400°C (2,550°F).

ʻIke ʻia kēia mau ʻāpana Ferritic i ʻoi aku ka kiʻekiʻe o ka hoʻouka ʻana i ka ʻili, ka resistivity kiʻekiʻe a me ka haʻahaʻa haʻahaʻaNickel Chrome(NiCr) hiki ke unuhi i nā mea liʻiliʻi i ka noi a me ka mālama kaumaha. Hiki ke alakaʻi i nā mahana hana ʻoi aku ka lōʻihi o ke ola ʻana. Hoʻokumu ʻia nā Aluminum Aluminum Iron Chrome i kahi Aluminum Oxide hina hina (Al2O3) ma nā mahana ma luna o 1,000°C (1,832°F) e hoʻonui ai i ka pale ʻana a me ka hana ʻana ma ke ʻano he insulator uila. ʻO ka hoʻokumu ʻana o ka oxide i manaʻo ʻia he mea hoʻokaʻawale iā ia iho a pale aku i ka pōkiʻi pōkole inā pili ka metala i ka metala. He haʻahaʻa ka ikaika mechanical ka hao Chrome Aluminum i ka hoʻohālikelike ʻiaNickel Chromemea a me ka ikaika kolo haʻahaʻa.
