Tam sim no, lub ntsiab kev tsoos ib puag ncig thiab kev siv cov khoom siv roj teeb, cov khoom siv superalloys, cov cuab yeej siv roj xis, thiab cov khoom sib nqus. Cobalt siv nyob rau hauv daim ntawv ntawm cov tebchaw yog tsuas yog siv los ua catalysts, desiccants, reagents, pigments, thiab dyes. Cobalt -60}} yog cov khoom siv xov tooj cua dav hlau uas tau siv dav hauv kev soj ntsuam kev tsom xam; hauv electroplating, corrosion, thiab catalysis for tracer kawm; thiab hauv cov tshuaj rau kev kuaj hluav taws xob thiab kev kho mob.
Cobalt yog ib qho ntawm ob peb cov ntaub ntawv metallic uas nyob twj ywm magnetised tom qab tsuas yog ib qho magnetisation. Qhov kub tshaj plaws ntawm cov hlauetisation yog ploj hauv lub hwj chim ntawm cov cua sov yog lub npe hu ua txoj kev foom. Thaum lub sij hawm sib txig sib txig ntawm hlau yog 769 degree thiab ntawm Nickel yog 358 degree yog 358 degree, nyob rau hauv ib puag ncig tshee, zoo tib yam hlau poob yuav luag ib-peb ntawm nws cov hlauetism. Cobalt steel hlau, txawm li cas los, tsuas yog poob 2% -3.5% ntawm nws cov hlauetism. Vim nws cov khoom sib nqus zoo tshaj plaws, cobalt yog dav siv nyob rau hauv kev tsim cov khoom lag luam siab hlau nplaum.
Cov ntaub ntawv sib nqus yog cov ntaub ntawv ua haujlwm tseem ceeb uas ua lub luag haujlwm tseem ceeb hauv kev lag luam hluav taws xob thiab cov neeg ua haujlwm siab. Cobalt yog siv hauv cov khoom sib nqus raws li hauv qab no: 70% hauv Alnico Tas nrho cov hlau nplaum tas li, thiab 10% nyob rau hauv lwm cov hlau tsis tshua muaj hlau nplaum cov ntaub ntawv.
