    ʻO ke kinikini FeCrAl (Iron-Chromium-Aluminum) kahi kinikini kūpaʻa wela kiʻekiʻe i haku ʻia me ka hao, chromium, a me ka alumini, me nā liʻiliʻi o nā mea ʻē aʻe e like me ka silicon a me ka manganese. Hoʻohana nui ʻia kēia mau kinikini i nā noi e pono ai ke kūpaʻa kiʻekiʻe i ka oxidation a me ke kūpaʻa wela maikaʻi loa, e kūpono ai no ka hoʻohana ʻana i nā mea hoʻomehana uila, nā umu ʻoihana, a me nā noi wela kiʻekiʻe e like me nā coils hoʻomehana, nā mea hoʻomehana radiant, a me nā thermocouples.

    1. Nā Waiwai Koʻikoʻi o ka FeCrAl Alloy:

    1. Ke kū'ē kiʻekiʻe: Loaʻa i nā mea hoʻohuihui FeCrAl kahi kū'ē uila kiʻekiʻe, kahi e kūpono ai no ka hoʻohana ʻana i nā mea hoʻomehana.
    2. Ke kū'ē'ē'ana i ka'okikene maika'i loa: Ho'okumu ka'ike alumini i kahi papa'okikene pa'a ma luna o ka'ili, e hā'awi ana i ka palekana ikaika e kū'ē i ka'okikene'ana a hiki i nā mahana ki'eki'e.

    3. Ikaika Mahana Kiʻekiʻe: Mālama lākou i ko lākou ikaika mechanical a me ke kūpaʻa dimensional i nā mahana kiʻekiʻe, e kūpono ai lākou no nā wahi wela kiʻekiʻe.
    4. Maikaʻi ke ʻano: Hiki ke hana maʻalahi ʻia nā mea hoʻohuihui FeCrAl i nā uea, nā lipine, a i ʻole nā ​​​​ʻano ʻē aʻe i hoʻohana ʻia no ka hoʻomehana uila.
    5. Ke kū'ē'ē'ana i ka pala: Ke kū'ē nei ka metala i ka pala ma nā'ano like'ole, e ho'onui ana i kona kūpa'a.
