Cov hlau tsis kam tuaj yeem raug cais raws li Iron Chrome Txhuas (FeCrAl), Nickel Chrome (NiCr), Copper Nickel (CuNi), thiab Nickel Iron (NiFe) alloys. Yog tias koj daim ntawv thov xav tau qhov kub thiab txias, Iron Chrome Aluminium alloy yuav yog qhov kev xaiv zoo tshaj plaws, qhov twg zoo li koj daim ntawv thov xav tau cov hlau kom muaj zog txaus ntawm qhov kub thiab txias, Nickel Chrome yuav yog qhov kev xaiv zoo dua. Txhua hom alloy muaj qee yam sib txawv.
Hlau Chrome Txhuas (FeCrAl) alloys yog cov khoom siv siab ua haujlwm feem ntau siv rau hauv cov ntawv thov nrog kev ua haujlwm siab tshaj plaws txog 1,400 degree (2,550 degree F).
Cov alloys muaj xws li: KAPM, KA1, KAF, KD, ALK
