Ma Aloyi a Iron Chrome Aluminium Resistance Alloys
Ma aloyi a Iron Chrome Aluminium (FeCrAl) ndi zinthu zosagwira ntchito kwambiri zomwe zimagwiritsidwa ntchito popanga zinthu zomwe zimakhala ndi kutentha kwambiri mpaka 1,400°C (2,550°F).
Ma aloyi a Ferritic awa amadziwika kuti ali ndi kuthekera kokweza pamwamba kwambiri, kulimba mtima kwambiri komanso kachulukidwe kakang'ono kuposa njira zina za Nickel Chrome (NiCr) zomwe zimatha kumasulira kuzinthu zochepa pakugwiritsira ntchito komanso kupulumutsa kulemera. Kutentha kwapamwamba kwambiri kungapangitsenso moyo wautali. Iron Chrome Aluminiyamu aloyi amapanga kuwala kotuwa Aluminiyamu Oxide (Al2O3) pa kutentha pamwamba pa 1,000°C (1,832°F) zomwe zimawonjezera kukana dzimbiri komanso zimagwira ntchito ngati chotchingira magetsi. Mapangidwe a okusayidi amaonedwa kuti ndi odziteteza okha ndipo amateteza kufupikitsa kuzungulira pakachitika chitsulo kupita kuzitsulo. Ma aluminiyamu a Iron Chrome ali ndi mphamvu zochepa zamakina poyerekeza ndi zida za Nickel Chrome komanso mphamvu zotsika.
