kan-thal D fecral alloy waya

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 Dndi yogwiritsidwa ntchito pa kutentha mpaka 1300 ° C (2370 ° F).

Mtundu uwu wa waya wa Kanthal supirira dzimbiri la sulfure komansoKanthal A1. Waya wa Kanthal D nthawi zambiri umapezeka m'zida zam'nyumba monga zotsukira mbale, zida za ceramic zopangira heater, ndi zowumitsira zovala. Itha kupezekanso m'mafakitale, omwe nthawi zambiri amawotcha ng'anjo.Kanthal A1Imasankhidwa nthawi zambiri kuti ipange ng'anjo yayikulu yamafakitale chifukwa champhamvu yake yolimbana ndi dzimbiri, kukana kwa dzimbiri bwino, komanso kutentha kwambiri komanso kukwawa kwamphamvu. Chimodzi mwazabwino zazikulu za Kanthal A1 kuposa Kanthal D ndikuti sichimawonjezera oxidize.

Kutengera resistivity chofunika, pazipita ntchito kutentha, ndi dzimbiri chikhalidwe cha element, mungafune kusankha Kanthal A-1 kapena Kanthal D waya.
