Kanthal wire ndi ferritic iron-chromium-aluminium (FeCrAl) alloy. Simachita dzimbiri mosavuta kapena kutulutsa okosijeni m'mafakitale ndipo imalimbana kwambiri ndi zinthu zowononga.

Waya wa Kanthal uli ndi kutentha kwambiri kuposa waya wa Nichrome. Poyerekeza ndi Nichrome, ili ndi katundu wokwera pamwamba, wopinga kwambiri, mphamvu zokolola zambiri, komanso kachulukidwe kakang'ono. Waya wa Kanthal umakhalanso nthawi 2 mpaka 4 kuposa waya wa Nichrome chifukwa chapamwamba kwambiri makutidwe ndi okosijeni komanso kukana madera a sulfuric.

Kanthal A1ndi yogwiritsidwa ntchito pa kutentha mpaka 1400 ° C (2550 ° F). Mtundu uwu wa Kanthal ndiye chisankho chabwino kwambiri cha waya wotsutsa ntchito zazikulu zamakampani. Ilinso ndi mphamvu yokwera pang'ono kuposaKanthal D.

Kanthal A1amagwiritsidwa ntchito kwambiri potenthetsa zinthu m'mafakitale akuluakulu monga ng'anjo za mafakitale (zomwe zimapezeka nthawi zambiri mumagalasi, zoumba, zamagetsi, ndi mafakitale azitsulo). Kulimbana kwake kwakukulu komanso kutha kupirira zinthu popanda oxidation, ngakhale mumlengalenga wa sulfure ndi wotentha, kumapangitsa Kanthal A1 kukhala chisankho chodziwika bwino pochita zinthu zotentha kwambiri. Waya wa Kanthal A1 ulinso ndi kukana konyowa konyowa komanso kutenthetsa komanso kukwawa kwamphamvu kuposa Kanthal D, zomwe zimapangitsa kukhala chisankho chodziwika bwino pamafakitale akuluakulu.
