FeCrAl alloy 0Cr27Al7Mo2 CrAl siab kub kuj Alloy Resistance Hlau
FeCrAl alloy yog siab tiv taus thiab hluav taws xob cua sov alloy. Fecral alloy tuaj yeem ncav cuag cov txheej txheem kub ntawm 2192 txog 2282 F, coj mus rau qhov ntsuas kub ntawm 2372F.
Txhawm rau txhim kho kev tiv thaiv oxidation muaj peev xwm thiab ua kom lub neej ua haujlwm, peb feem ntau muab ntxiv ntawm cov av tsis tshua muaj hauv cov hlau, xws li La + Ce, Yttrium, Hafnium, Zirconium, thiab lwm yam.
Nws feem ntau yog siv rau hauv hluav taws xob rauv, iav sab saum toj hobs, quartz tube rhaub, resistors, catalytic converter, cua sov ntsiab thiab lwm yam.
