    Motsoako oa FeCrAl (Iron-Chromium-Aluminum) ke motsoako o hanyetsanang le mocheso o phahameng o entsoeng haholo-holo ka tšepe, chromium le aluminium, ka likarolo tse ling tse nyane tse kang silicon le manganese. Metsoako ena e sebelisoa haholo lits'ebetsong tse hlokang ho hanyetsana ho hoholo ha oxidation le ho hanyetsa mocheso ho hoholo, e leng se etsang hore e be e loketseng ho sebelisoa likarolong tsa ho futhumatsa tsa motlakase, liontong tsa indasteri, le lits'ebetsong tsa mocheso o phahameng joalo ka likhoele tsa ho futhumatsa, li-heater tse khanyang, le li-thermocouple.
