waya wa kanthal a1 wowala kapena wothira fecral alloy

Kanthal A1imagwiritsidwa ntchito kutentha mpaka 1400°C (2550°F). Mtundu uwu wa Kanthal ndiye chisankho chabwino kwambiri cha waya wotsutsa ntchito zazikulu zamafakitale. Ulinso ndi mphamvu yokulirapo pang'ono kuposaKanthal D.

Tili ndi katundu, ngati mukufuna, chonde titumizireni uthenga mwachangu.

Kanthal A1imagwiritsidwa ntchito kwambiri potenthetsera zinthu m'mafakitale akuluakulu monga ng'anjo zamafakitale (zomwe zimapezeka kwambiri m'mafakitale agalasi, zadothi, zamagetsi, ndi zitsulo). Kulimba kwake kwakukulu komanso kuthekera kwake kupirira zinthu popanda okosijeni, ngakhale m'mlengalenga wotentha ndi sulfure, kumapangitsa Kanthal A1 kukhala chisankho chodziwika bwino pochita ndi zinthu zotenthetsera zazikulu. Waya wa Kanthal A1 ulinso ndi kukana dzimbiri konyowa komanso mphamvu yotentha komanso yokwera kuposa Kanthal D, zomwe zimapangitsa kuti ikhale chisankho chodziwika bwino pamafakitale akuluakulu.

Waya wa Kanthal ndi aloyi wa ferritic iron-chromium-aluminium (FeCrAl). Siumazizira kapena kusungunuka mosavuta m'mafakitale ndipo umalimbana bwino ndi zinthu zowononga.

Waya wa Kanthal uli ndi kutentha kwakukulu kogwira ntchito kuposa waya wa Nichrome. Poyerekeza ndi Nichrome, uli ndi katundu wapamwamba pamwamba, mphamvu yolimba kwambiri, mphamvu yogwira ntchito kwambiri, komanso kukhuthala kochepa. Waya wa Kanthal umakhalanso wautali nthawi ziwiri mpaka zinayi kuposa waya wa Nichrome chifukwa cha mphamvu zake zabwino zosungunuka komanso kukana kwake ku sulfure.
