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

Cov hlau Kanthal muaj qhov kub siab tshaj plaws ua haujlwm dua li cov hlau Nichrome. Piv rau Nichrome, nws muaj qhov hnyav dua ntawm qhov chaw, tiv taus siab dua, muaj zog dua, thiab qhov ceev qis dua. Cov hlau Kanthal kuj kav ntev dua 2 txog 4 npaug dua li cov hlau Nichrome vim nws cov khoom oxidation zoo dua thiab tiv taus cov chaw 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 tiv thaiv rau cov ntawv thov kev lag luam loj. Nws kuj muaj lub zog tensile siab dua me ntsis dua liKanthal D.

Kanthal A1feem ntau yog siv rau hauv cov khoom cua sov hauv cov ntawv thov kev lag luam loj xws li cov cub tawg kev lag luam (feem ntau pom muaj nyob rau hauv cov iav, ceramics, electronics, thiab steel industries). Nws lub zog tiv taus siab thiab muaj peev xwm tiv taus cov ntsiab lus yam tsis muaj oxidation, txawm tias nyob rau hauv sulfuric thiab kub atmospheres, ua rauKanthal A1ib qho kev xaiv nrov thaum cuam tshuam nrog cov khoom siv cua sov loj. Kanthal A1 hlau kuj muaj kev tiv thaiv xeb ntub dej siab dua thiab muaj zog kub thiab nkag siab dua li Kanthal D, ua rau nws yog ib qho kev xaiv nrov rau kev siv hauv kev lag luam loj.
