Sharaxaada Guud
Daawaynta FeCrAl waxa lagu sameeyaa heerkul sare, bir-chromium-aluminium alloy ferritic ah kaas oo loo isticmaali karo heerkul ilaa 1350degrees. Codsiyada caadiga ah ee0Cr21Al6Nb waa sida korontowalxaha kululayntas in foornooyinka kulaylka sareeyo ee daaweynta kulaylka, ceramics, galaaska, birta, iyo warshadaha elektarooniga ah.
Tilmaam:
Oo leh nolol dheer oo adeeg ah U isticmaali karaa si toos ah. Marka lagu isticmaalo danab la qiimeeyay, ma jirto arrin kacsan. Waa ilaalinta deegaanka silig kuleyliyaha. Iyo beddelka siliga nichrome-ka qaaliga ah. Waxa lagu beddeli karaa si waafaqsan shuruudaha macaamiisha
FeCrAl Alloys waxaa lagu gartaa caabbinta oksaydheynta oo aad u wanaagsan iyo qaab aad u wanaagsan oo degenaansho taasoo keentay nolol curiye dheer.
Caadi ahaan waxaa loo isticmaalaa walxaha kuleyliyaha korantada ee foornooyinka warshadaha iyo qalabka guriga.
Fe-Cr-Al alloy oo leh iska caabin sare iyo heerkulka adeeg ee ka badan kan Alloynka NiCr sidoo kale wuxuu leeyahay qiimo hoose.
Codsiyada
0Cr21Al6 Birta-chrome-aluminium-ka caabiyaha korantada ayaa si weyn loogu isticmaalaa samaynta walxaha kuleylka korantada ee qalabka guriga iyo foornooyinka warshadaha. Codsiyada caadiga ah waa birta fidsan, makiinadaha feereysta, kuleyliyaha biyaha, balaastigga bakhtiya, biraha alxanka, walxaha tuubada galka birta leh iyo walxaha kartoojka
aagga codsiga
Alaabadayada waxaa si weyn loogu isticmaalaa qalabka daaweynta kulaylka, qaybaha baabuurta, birta iyo wax soo saarka birta,
warshadaha aluminium, qalabka biraha, qalabka petrochemical, mishiinada dhalooyinka, mishiinada dhoobada,
mashiinada cuntada, mashiinada dawooyinka, iyo warshadaha tamarta korontada.
