Nā Alloys Pale ʻAlumini Hao Chrome
ʻO nā mea hoʻohuihui Iron Chrome Aluminum (FeCrAl) he mau mea kūpaʻa kiʻekiʻe i hoʻohana pinepine ʻia i nā noi me nā mahana hana kiʻekiʻe loa a hiki i 1,400°C (2,550°F).

Ua ʻike ʻia kēia mau mea hoʻohui Ferritic he kiʻekiʻe ko lākou hiki ke hoʻouka i ka ʻili, ke kū'ē kiʻekiʻe a me ka haʻahaʻa o ka density ma mua o nā koho ʻē aʻe o Nickel Chrome (NiCr) hiki ke unuhi i ka liʻiliʻi o nā mea i ka noi a me ka mālama ʻana i ke kaumaha. Hiki i nā mahana hana kiʻekiʻe ke alakaʻi i ke ola lōʻihi o nā element. Hoʻokumu nā mea hoʻohui Iron Chrome Aluminum i kahi Aluminum Oxide hina māmā (Al2O3) ma nā mahana ma luna o 1,000°C (1,832°F) e hoʻonui ai i ke kū'ē ʻana i ka corrosion a hana pū kekahi ma ke ʻano he insulator uila. Manaʻo ʻia ka hoʻokumu ʻana o ka oxide he mea hoʻokaʻawale ponoʻī a pale aku i ka pōʻai pōkole i ka hanana o ka hoʻopili ʻana o ka metala i ka metala. ʻOi aku ka ikaika mechanical o nā mea hoʻohui Iron Chrome Aluminum i ka hoʻohālikelike ʻia me nā mea Nickel Chrome a me ka ikaika kolo haʻahaʻa.
