Eia kekahi, ʻoi aku ka pipiʻi o SmCo5 ma mua o Sm2Co17. No laila, manaʻo ka hapa nui o ka poʻe SmCo5 magnet ʻaʻohe mea maikaʻi ma luna o Sm2Co17 magnet a laila ua kaupalena ʻia ke kahua noi no SmCo5 magnet. Eia naʻe, hiki ke hoʻohana ʻia ʻo SmCo5 a pono paha i kekahi mau hihia:
1. Manaʻo paʻa o nā huahana:Ua hoʻomohala ʻia ʻo SmCo5 magnet ma mua o Sm2Co17 magnet. A ua hoʻāʻo ʻia ka hoʻolālā ʻana o kekahi mau huahana e hoʻohana ana i nā magnet SmCo5 a hōʻoia ʻia no ka kamaʻilio microwave, pale a me nā mākeke koa. ʻOi aku ka lōʻihi o ka manawa a i ʻole ke kumukūʻai kiʻekiʻe e hōʻoia i ka hoʻolālā hou ʻia me nā magnet Sm2Co17. ʻAʻole nui ka ʻokoʻa ma waena o SmCo5 a me Sm2Co17. I mea e mālama pono ai i nā waiwai huahana, hoʻohana mau ʻia ka SmCo5 magnet me ka nānā ʻole i ka pono o Sm2Co17 magnet.
2. Maʻalahi e magnetize:'O ka mea ma'amau, he 15 a 20 kOe ka Hcj no na magnet SmCo5, oiai ua oi aku i ka 20 kOe no na magnet Sm2Co17. He mea maʻalahi ke hoʻokalakupua i nā magnet me ka Hcj haʻahaʻa i ka saturation. Pono kekahi mau mea kūʻai aku i nā mea hoʻokalakupua SmCo i hoʻolako ʻia i nā huahana unmagnetized a hui pū ʻia e magnetized e kā lākou magnetizer a me ka magnetizing coil. Hoʻolako ʻia ka hapa nui o nā mea kūʻai aku me nā mea hana magnetizing me ka haʻahaʻa haʻahaʻa no nā mea magnetic i hoʻohana nui ʻia, e like me Ferrite, NdFeB a i ʻole.Alnico magnets, oiai haahaa loa no ka magnetize Sm2Co17 magnet i saturation. He pipiʻi ke kūʻai ʻana i nā mea hoʻokalakupua kiʻekiʻe kiʻekiʻe no nā magnet Sm2Co17 kūikawā. A laila koi ʻia nā magnet SmCo5.
3. Maʻalahi i ka mīkini:SmCo5 i oi machinability ma mua o Sm2Co17, a maʻalahi e hana paʻakikī shape a me ka nui e pono ai.
No ke aha SmCo5 magnet i oi pipiʻi ma mua o Sm2Co17? ʻO ke kumu nui mai ka haku ʻana omagnet maka mea. No ka Sm2Co17 magnet, ʻo ka haku mele Sm, Co, Cu, Fe a me Zr, a ʻo nā mea kumukūʻai ʻo Co ka helu ʻana no 50% a puni a ʻo Sm helu no 25% a puni. No ka SmCo5 magnet, ka mea haku mele Sm helu no 30% a puni a Co helu no 70% a puni, no ka Pr + Sm helu no 30% a Co helu no 70%. He ʻano metala koʻikoʻi ʻo Co.
