Intambo yeKanthal iyi-ferritic iron-chromium-aluminium (FeCrAl) alloy. Ayigqwali kalula noma i-oxidize ezisetshenziswa ezimbonini futhi inokumelana okuhle kakhulu nezinto ezigqwalisayo.

Intambo yeKanthal inokushisa okuphezulu kokusebenza kunentambo yeNichrome. Uma iqhathaniswa neNichrome, inomthwalo ophezulu wobuso, ukumelana okuphezulu, amandla aphezulu okukhiqiza, kanye nobuningi obuphansi. Intambo yeKanthal iphinde ihlale isikhathi eside izikhathi ezi-2 kuya kwezi-4 kunentambo yeNichrome ngenxa yezakhiwo zayo ezinhle kakhulu zokuxiliswa kanye nokumelana nezimo zesulfuric.

I-Kanthal A1isetshenziswa emazingeni okushisa afinyelela ku-1400°C (2550°F). Lolu hlobo lwe-Kanthal luyindlela engcono kakhulu yocingo lokumelana nezicelo ezinkulu zezimboni. Inamandla okudonswa aphezulu kancane kune-I-Kanthal D.

I-Kanthal A1ivame ukusetshenziswa kakhulu ekufudumaleni kwezinto ezisetshenziswayo ezimbonini ezinkulu njengezitofu zezimboni (ezivame ukutholakala engilazini, ezintweni zobumba, ezintweni zikagesi, kanye nasezimbonini zensimbi). Ukumelana kwayo okuphezulu kanye nekhono lokumelana nezinto ngaphandle kokushiswa, ngisho nasezimoyeni ezishisayo nezine-sulfuric, kwenzaI-Kanthal A1ukukhetha okuthandwayo lapho usebenzisana nezinto zokushisa ezinkulu. Intambo ye-Kanthal A1 nayo inokumelana nokugqwala okumanzi okuphezulu kanye namandla aphezulu okushisa nokukhukhuleka kune-Kanthal D, okwenza kube ukukhetha okuthandwayo kwezicelo ezinkulu zezimboni.
