Cobalt waa bir dhalaalaysa bir-cawlan, xoogaa adag oo jajaban, ferromagnetic, waxayna la mid tahay birta iyo nikkel ee engegnaanta, xoogga adkaysiga, sifooyinka farsamada, guryaha heerkulbeegyada, iyo dabeecada korantada.Magnetismku wuu baaba'aa marka lagu kululeeyo 1150 ℃.Budada cobalt ee biraha ah ee ay soo saarto habka dhimista hydrogen waxay si iskiis ah ugu shidi kartaa kobalt oxide hawada.Oxidation waxay ku dhacdaa heerkulka sare.Marka la kululeeyo, cobalt waxay si xoog leh uga falcelisaa ogsijiin, baaruud, koloriin, bromine, iwm., si ay u sameeyaan isku dhisyo u dhigma.Cobalt waxa ay ku milmaysaa asiidh-ka-milo waxana ay ku dhex milmay qiiqa nitric acid iyada oo samaynaysa filim oksaydh ah.Cobalt waxaa si tartiib ah u xardhay hydrofluoric acid, ammonia iyo sodium hydroxide.Cobalt waa walxo ceeriin ah oo muhiim u ah soo saarista alwaaxyada kulaylka u adkeysanaya, Alloys adag, alloys-ka-hortagga daxalka, alloys magnetka iyo cusbada cobalt ee kala duwan.Cobalt waa bir amphoteric ah.

Qalabka jirka iyo kiimikaad ee cobalt ayaa go'aamiya in ay tahay alaabta ceeriin ee muhiimka ah ee soo saarista alwaaxyada kulaylka u adkaysta, carbide cemented, alloys anti-corrosion, alloys magnetic iyo cusbada cobalt ee kala duwan.Alloys-ku-saleysan-kobalt-ku-saleysan ama bir-ku-jirta-ku-jirta waxaa loo isticmaalaa sida dabbooyin, impellers, conduits, matoorada jet-ka, matoorada gantaallada, qaybaha gantaallada iyo qaybaha kala duwan ee-load sare kulaylka u adkaysta ee qalabka kiimikada iyo qalabka biraha muhiimka ah ee warshadaha tamarta atamka.Cobalt-ku-xidhaha binder-ka budada ah wuxuu hubin karaa in karbidhidka sibidhka uu leeyahay xoogaa adag.Alloys Magnetic waa walxo lagama maarmaanka u ah warshadaha elektiroonigga ah iyo kuwa elektiroonigga ah ee casriga ah, oo loo isticmaalo soo saarista qaybo kala duwan oo ah acoustic, indhaha, korantada iyo qalabka magnetic.Cobalt sidoo kale waa qayb muhiim ah oo ka mid ah alloys magnetic joogto ah.Warshadaha kiimikada, cobalt waxaa loo isticmaalaa marka lagu daro superalloys iyo alloys anti-corrosion, laakiin sidoo kale dhalooyinka midabka leh, midabada, dhaldhalaalka iyo kicinta, qalajiyaha iyo wixii la mid ah.Intaa waxaa dheer, isticmaalka kobaltku wuxuu leeyahay heerka kobaca ugu sarreeya ee qaybta batteriga.

Cobalt-ka birta ah waxaa inta badan loo isticmaalaa in lagu sameeyo alloys.Daawaha salka Cobalt waa erey guud oo ah hal ama dhowr alaabo oo ka samaysan cobalt iyo chromium, tungsten, iron iyo nikkel.Qalabka birta ah ee ka kooban qadar go'an oo cobalt ah ayaa si weyn u wanaajin kara caabbinta xirashada iyo jarista waxqabadka birta.Carbide Starlite oo ka kooban in ka badan 50% cobalt ma lumin doono adkaanshihiisa asalka ah xitaa haddii lagu kululeeyo 1000 ° C, hadda carbide-kan ayaa noqday walxaha ugu muhiimsan ee loo isticmaalo inta u dhaxaysa qalabka wax lagu gooyo ee dahabku ka kooban yahay iyo aluminium.Qalabkan, kobaltku wuxuu isku daraa miraha carbide birta kale ee ka kooban alloy-ga, si ay daawadu u leedahay adkeysi sare waxayna yareysaa dareenka saameynta.Alaabtaani waxay isku dhejisan tahay oo lagu dhejiyay dusha sare ee qaybaha, taas oo kordhin karta nolosha qaybaha 3 ilaa 7 jeer.Alloys-ka ugu badan ee loo isticmaalo tignoolajiyada hawada sare waa nikkel-ku-saleysan, sidoo kale alwaaxyada kobalt-ku-saleysan waa la isticmaali karaa, laakiin "qaabka xoogga leh" ee labada alloys waa ka duwan yahay.Awoodda aluminium-ku-salaysan ee nikkel-ku-salaysan oo ay ku jiraan titanium iyo aluminium waa sarreeyaa sababtoo ah samaynta walax adag oo ka kooban NiAl (Ti), marka heerkulka hawlgalka uu sarreeyo, qaybaha walxaha adag ee wajiga ayaa loo wareejiyaa xal adag, ka dibna daawaha si degdeg ah u lumin awoodda.Cadaadiska kulaylka ee alwaaxyada cobalt-ku salaysan waxaa sabab u ah samaynta carbides refractory, kuwaas oo aan sahlanayn in loo beddelo xalal adag, iyo waxqabadka faafinta waa yar yahay.Marka heerkulku ka sarreeyo 1038 ° C, faa'iidooyinka alwaaxyada cobalt-ku-salaysan ayaa si buuxda loo soo bandhigay.Waxtarka sare, matoorada heerkulka sare leh, alwaaxyada cobalt-ku-salaysan waa sax.
