Kanthal hlau yog ferritic hlau-chromium-aluminium (FeCrAl) alloy.Nws tsis yooj yim xeb lossis oxidize hauv cov ntawv thov kev lag luam thiab muaj kev tiv thaiv zoo rau cov ntsiab lus corrosive.

Kanthal hlau muaj qhov kub siab tshaj plaws ua haujlwm tshaj li Nichrome hlau.Muab piv rau Nichrome, nws muaj qhov hnyav dua qhov hnyav, muaj zog dua, muaj zog tawm los ntau dua, thiab qis dua.Kanthal hlau tseem kav ntev li 2 mus rau 4 npaug ntev dua Nichrome hlau vim nws cov khoom muaj zog oxidation zoo dua thiab tsis kam mus rau ib puag ncig sulfuric.

Kanthal A1yog siv rau qhov kub txog li 1400 ° C (2550 ° F).Hom Kanthal no yog qhov kev xaiv zoo tshaj plaws ntawm cov hlau tsis kam rau cov ntawv thov loj.Nws kuj muaj lub zog tensile me ntsis duaKanthal D.

Kanthal A1feem ntau yog siv rau hauv cov khoom cua sov hauv kev lag luam loj xws li kev lag luam furnaces (feem ntau pom hauv iav, ceramics, electronics, thiab steel industries).Nws muaj kev tiv thaiv siab thiab muaj peev xwm tiv taus cov ntsiab lus tsis muaj oxidation, txawm tias nyob rau hauv sulfuric thiab kub cua, ua rau Kanthal A1 yog qhov kev xaiv nrov thaum cuam tshuam nrog cov cua kub loj.Kanthal A1 hlau kuj muaj qhov ntub dej ntau dua thiab muaj zog dua kub thiab nkag siab duaKanthal D, ua rau nws yog qhov kev xaiv nrov rau kev lag luam loj.
