I-Kanthal AF yi-ferritic iron-chromium-aluminium alloy (FeCrAl alloy) ukuze isetyenziswe kumaqondo obushushu ukuya kwi-1300 ° C (2370 ° F). I-alloy ibonakaliswe ngokumelana okugqwesileyo kwe-oxidation kunye nozinzo oluhle kakhulu lwefomu olukhokelela ekubeni ludeubomi element.Usetyenziso oluqhelekileyo lweKanthal AF lufana nezinto zokufudumeza zombane kwiziko loshishino
