Ikwaziwa njengemagnethi ye-cobalt ye-samarium, i-samarium cobalt umazibuthe osisigxina, i-samarium cobalt umazibuthe osisigxina, imagnethi yomhlaba enqabileyo yecobalt, njl. , ukucofa nokuntywila. Ukuya kuthi ga kwi-350 ℃, iqondo lobushushu elibi alikhawulelwanga, xa ubushushu bokusebenza bungaphezulu kwe-180 ℃, ukuzinza kwayo kobushushu kunye nokuzinza kweekhemikhali ziphezulu kunezixhobo zemagnethi ezisisigxina zeNdFeB.
Enye yemagnethi esisigxina yomhlaba enqabileyo, kukho ubukhulu becala amacandelo amabini: SmCo5 kunye ne-Sm2Co17.Imveliso yamandla amakhulu wemagnethi, ukunyanzeliswa okuthembekileyo kunye nokumelana nobushushu obuphezulu. Sisizukulwana sesibini seemveliso zomhlaba ezinqabileyo.
Imagnethi ye-cobalt yaseSamarium (i-SmCo) inamandla okuchasa umhlwa, i-rust-proof kunye nokumelana nobushushu obuphezulu kunemagnethi ye-NdFeB. Iimagnethi ze-SmCo zihlengahlengiswa nge-alloying, eya kutshintsha ngokupheleleyo indlela yokuhamba kaloliwe yehlabathi.
Inokumelana ne-corrosion enamandla kunye nokumelana ne-oxidation; ngoko isetyenziswa ngokubanzi kwi-aerospace, ukukhusela kunye noshishino lomkhosi, izixhobo ze-microwave, unxibelelwano, izixhobo zonyango, izixhobo, iimitha, izixhobo ezahlukeneyo zokuhambisa imagnethi, abenzi boluvo, iiprosesa zemagneti, iimotor, i-magnetic cranes Linda.
