I-Kanthal AF iyi-Ferritic Iron-Chromium-Aluminium Alloy (FECRAL ALLOY) yokusebenzisa amazinga okushisa aze afike ku-1300 ° C (2370 ° F). I-alloy ibonakala ngokumelana ne-oxidation enhle kakhulu nokuqina kwefomu okuhle okuholela esikhathini esideImpilo yenyama.Izicelo ezijwayelekile ze-kanthal af zinjengezinto zokushisa zikagesi ezindlini zezimboni
