I-Iron Chrome Aluminium Resistance Alloys
Ama-alloys e-Iron Chrome Aluminium (FeCrAl) yizinto ezimelana kakhulu nezivamile ezisetshenziswa ezinhlelweni zokusebenza ezinamazinga okushisa aphezulu afika ku-1,400°C (2,550°F).

Lawa ma-alloys e-Ferritic aziwa ngokuba namandla aphezulu okulayisha phezulu, ukumelana okuphezulu nokuminyana okuphansi kunezinye izindlela ze-Nickel Chrome (NiCr) ezingahumushela ezintweni ezincane ekusetshenzisweni nasekukongeni isisindo. Amazinga okushisa aphezulu aphezulu okusebenza nawo angaholela empilweni ende yezinto. I-Iron Chrome Aluminium alloys yenza i-Aluminium Oxide (Al2O3) empunga ngokukhanyayo emazingeni okushisa angaphezu kuka-1,000°C (1,832°F) enyusa ukumelana nokugqwala futhi isebenza njengesivikelo sikagesi. Ukwakheka kwe-oxide kuthathwa njenge-self-insulating futhi ivikela ekujikelezeni okufushane uma kwenzeka ukuxhumana kwensimbi kuya kwensimbi. Ama-alloys e-Iron Chrome Aluminium anamandla okusebenza aphansi uma eqhathaniswa nezinto ze-Nickel Chrome kanye namandla aphansi okukhasa.
