Barra minn hekk, il-kalamiti SmCo għandhom karatteristiċi oħra:
Prestazzjoni affidabbli: Il-kalamiti SmCo huma estremament reżistenti għad-demagnetization li jagħmluhom affidabbli f'ħafna ambjenti.
Reżistenza għall-korrużjoni u l-ossidazzjoni: Minħabba l-kontenut baxx ta 'ħadid fil-materjal kompost, il-kalamiti SmCo għandhom reżistenza eċċellenti għall-korrużjoni.B'differenza NdFeB, kalamiti SmCo m'għandhomx bżonn electroplating.
Stabbiltà tat-temperatura: SmCo jista 'jżomm il-forza manjetika tiegħu f'temperaturi għoljin (249-300 ℃) u temperaturi baxxi ħafna (-232 ℃).
Materjali fraġli: Meta fis-sinterizzazzjoni, il-materjal jista 'jkun fraġli, minħabba li huwa fraġli u faċli biex jinqasam, l-ipproċessar għandu limitazzjonijiet, li l-metodi ta' pproċessar tradizzjonali ma jistgħux jaħdmu.Madankollu, jista 'jiġi mitħun, iżda biss jekk jintużaw ammont kbir ta' likwidu li jkessaħ.Dan għaliex il-likwidu li jkessaħ jista 'jimminimizza r-riskju ta' nar minn qsim termali u trab tat-tħin ossidizzat.
Applikazzjonijiet:
1. Muturi PM high-end.Il-muturi PM ġenerali ġeneralment jużaw kalamiti tal-ferrite jew kalamiti NdFeB.Iżda f'postijiet fejn it-temperatura taqbeż il-200 ℃ jew it-torque tal-stall huwa kbir, il-muturi SmCo PM biss huma kompetenti.
2. Apparati elettroakustiċi f'sistemi ta 'lawdspikers high-end.
3. Sistema ta 'strument affidabbli ħafna.Ħafna strumenti użati fl-ajruspazju, fl-avjazzjoni, mediċi u oqsma oħra għandhom jużaw kalamiti permanenti SmCo biex jiżguraw affidabilità għolja u sigurtà perfetta.
4. F'sistemi ta 'radar u komunikazzjoni estremament importanti, numru kbir ta' tubi tal-mewġ li jivvjaġġaw, magnetrons, tubi tal-ġiri, tubi tal-mewġ tal-ġiri, gyrotrons u apparati oħra tal-vakwu elettriċi huma użati, u kalamiti SmCo jagħmlu raġġi ta 'elettroni tul il-mixja tul mogħdija preskritta.
5. Estratturi manjetiċi SmCo f'bjar fondi taħt it-3000 metru, u drive manjetiku SmCo (pompa) f'ambjent ta 'temperatura għolja ta' 200 ℃.
6. Kap ta 'ġbid manjetiku, separatur manjetiku, bearing manjetiku, NMR, eċċ.
