Zogulitsa

Alloys a Iron Chrome Aluminium (FeCrAl) ndi zida zotsutsana kwambiri zomwe zimagwiritsidwa ntchito munthawi yotentha kwambiri mpaka 1,400 ° C (2,550 ° F).

Ma alloys a Ferritic amadziwika kuti ali ndi kuthekera kokulirapo pamwamba, kotsalira kotsika kwambiri komanso kachulukidwe kocheperako kuposa njira zina za Nickel Chrome (NiCr) zomwe zimatha kutanthauzira kuzinthu zochepa pakugwiritsa ntchito komanso kupulumutsa kulemera. Kutentha kwakukulu kogwirira ntchito kumathandizanso kukhala ndi moyo wautali. Alloys a Iron Chrome Aluminiyamu amapanga imvi yoyera ya Aluminium oxide (Al2O3) pamatenthedwe opitilira 1,000 ° C (1,832 ° F) omwe amachulukitsa kukana kwa dzimbiri komanso amakhala ngati opewera magetsi. Kupangika kwa oxide kumawerengedwa kuti kumadzitchinjiriza komanso kumateteza kuzungulirako kwakanthawi kochepa pazitsulo zachitsulo. Zipangizo za Iron Chrome Aluminiyamu zimakhala ndi mphamvu zochepa poyerekeza ndi zida za Nickel Chrome komanso mphamvu zochepa.
