I-Kanthal af yi-ferricuric i-iron-chromium-alloum alloy (i-fecral alloy) yokusetyenziswa kumaqondo obushushu ukuya kuthi ga kwi-1300 ° C (2370 ° F). I-alloy ibonakaliswa ngokuchasene ne-oxidation egqwesileyo kunye nokuzinza okuhle kakhulu okuphumela ixesha elideUbomi beLimen.Izicelo eziqhelekileyo zeKanthal af zinjengezinto zokufudumeza zombane kwiziko lemizi-mveliso
