FeCrAlkiʻekiʻe ke kū'ē a me ka uila hoʻomehana uila
FeCrAl pale a me ka hoʻomehana wela me nā hiʻohiʻona o ke kūpaʻa kiʻekiʻe, ka haʻahaʻa haʻahaʻa haʻahaʻa o ke kū'ē uila, ke kiʻekiʻe o ka hana ʻana, ke kūpaʻa corrosion maikaʻi ma lalo o ke kiʻekiʻe wela, a me ke kumu kūʻai haʻahaʻa.
Hoʻohana nui ʻia ia i ka umu uila ʻoihana, nā mea uila hale a me nā mea uila mamao infrared.
