Mazuva ano, mumashandisirwo mazhinji Alnico yakatsiviwa neNeodymium kana Samarium Cobalt magineti. Nekudaro, chivakwa chayo senge kugadzikana kwetembiricha uye kushanda kwakanyanya tembiricha inoita kuti Alnico magineti ive yakakosha mune mamwe misika yekushandisa.
1. High magnetic field. Residual induction yakakwira kusvika 11000 Gauss inenge yakafanana neSm2Co17 magineti, uyezve inogona kuburitsa yakakwirira magineti yakatenderedza.
2. Kupisa kwekushanda kwepamusoro. Kupisa kwayo kwakanyanya kushanda kunogona kukwira kusvika ku550⁰C.
3. High tembiricha kugadzikana: Alnico magineti ane akanakisa tembiricha coefficients chero magineti zvinhu. Alnico magineti inofanirwa kutorwa seyakanakisa sarudzo mune yakanyanya kupisa tembiricha maapplication.
4. Yakanakisa corrosion resistance. Alnico magineti haatani kuita ngura uye anogona kazhinji kushandiswa pasina chero kuchengetedzwa kwepamusoro
1. Easy to demagnetize: Yayo yakawanda yakaderera yekumanikidza simba Hcb yakaderera pane 2 kOe uye zvadaro zviri nyore kuita demagnetize mune imwe yakaderera demagnetizing munda, kunyangwe isina kubatwa nehanya.
2. Zvakaoma uye brittle. Inowanzoita kuputika uye kuputika.
1. Sezvo coercivity yeAlnico magineti yakaderera, chiyero chehurefu kusvika kudhayamita inofanira kuva 5: 1 kana yakakura kuitira kuti uwane nzvimbo yakanaka yekushanda yeAlnico.
2. Sezvo Alnico magineti ari nyore demagnetized nekusachengeta kubata, zvinokurudzirwa kuita magnetizing mushure megungano.
3. Alnico magineti inopa kudzikama tembiricha. Iyo inobuda kubva kuAlnico magineti inosiyana zvishoma nekuchinja kwekushisa, zvichiita kuti ive sarudzo yakanaka kune tembiricha inodzivirira maapplication, akadai sekurapa nemauto.
Zvirokwazvo isu hatisi Alnico magineti anogadzira, asi isu tiri nyanzvi mune magineti marudzi emagineti echigarire anosanganisira Alnico. Zvakare, edu pachedu akagadzirwa asingawanzo epasi magineti uye magineti maassemblies anozogonesa vatengi kuve nekutenga-kumira kwekutenga zvigadzirwa zvemagineti kubva kwatiri zviri nyore.
