Qalabka jidheed iyo kiimikaad ee kobaltku waxay go'aamiyaan inay tahay shay muhiim u ah soo saarida alaabo kulaylka u adkaysta, Alloys adag, alloys anti-corrosion, alloys magnet, iyo cusbada cobalt ee kala duwan.Sida binder ee biraha budada ah, waxay xaqiijin kartaa iska caabin gaar ah oo carbide sibidhka ah.Alloys-ka birlabku maaha kuwo ka yar agabka casriga ah ee elektiroonigga ah iyo warshadaha korantada.Waxaa loo isticmaalaa in lagu sameeyo qaybo kala duwan oo loogu talagalay codka, iftiinka, korontada iyo magnetismka.

Cobalt sidoo kale waa qayb muhiim ah oo ka mid ah alloys magnetic joogto ah.Warshadaha kiimikada, marka lagu daro alloys heerkul sare ah iyo alloys-ka-hortagga, kobalt waxaa sidoo kale loo isticmaalaa muraayadaha midabka leh, midabada, dhaldhalaalka iyo kicinta, qallajiye, iwm. Marka loo eego warbixinnada gudaha ee khuseeya, isticmaalka kobalt ee batteriga kaydinta Xirfadda, xirfadda alaabta dheemanka iyo xirfadda kicinta ayaa sidoo kale la sii ballaarin doonaa, si baahida loo qabo cobalt macdan ay kor u kacdo.
