Iron Chrome Aluminiomu Resistance Alloys
Iron Chrome Aluminiomu (FeCrAl) awọn ohun elo atako giga ti a lo ni igbagbogbo ni awọn ohun elo pẹlu awọn iwọn otutu ti o pọ julọ to 1,400°C (2,550°F).
Awọn irin-ajo Ferritic wọnyi ni a mọ lati ni agbara ikojọpọ dada ti o ga, resistivity ti o ga ati iwuwo kekere ju awọn ọna yiyan Nickel Chrome (NiCr) eyiti o le tumọ si ohun elo ti o kere si ni ohun elo ati awọn ifowopamọ iwuwo.Awọn iwọn otutu iṣẹ ṣiṣe ti o ga julọ le tun ja si igbesi aye eroja to gun.Iron Chrome Aluminiomu alloys dagba ina grẹy Aluminiomu Oxide (Al2O3) ni awọn iwọn otutu loke 1,000°C (1,832°F) eyi ti o mu ipata resistance bi daradara bi sise bi itanna insulator.Ibiyi ohun elo afẹfẹ jẹ idabobo ti ara ẹni ati aabo lodi si yiyi kukuru ni iṣẹlẹ ti irin si olubasọrọ irin.Iron Chrome Aluminiomu alloys ni kekere darí agbara nigba ti akawe si nickel Chrome ohun elo bi daradara bi kekere ti nrakò agbara.
