Matsatsing ana, lits'ebetsong tse ngata Alnico e nkeloe sebaka ke Neodymium kapa Samarium Cobalt makenete. Leha ho le joalo, thepa ea eona joalo ka botsitso ba mocheso le mocheso o phahameng o sebetsang haholo o etsa hore limatlase tsa Alnico e be tsa bohlokoa mebarakeng e meng ea kopo.
1. Matla a khoheli a phahameng. Residual induction e phahame ho 11000 Gauss hoo e batlang e tšoana le Sm2Co17 makenete, ebe e ka hlahisa matla a khoheli a phahameng ho potoloha.
2. Mocheso o phahameng oa ho sebetsa. Mocheso oa eona o phahameng oa ho sebetsa o ka ba holimo ho 550⁰C.
3. Boemo bo tsitsitseng ba mocheso: Limanete tsa Alnico li na le li-coefficients tse ntle ka ho fetisisa tsa mocheso oa thepa efe kapa efe ea makenete. Limanete tsa Alnico li lokela ho nkuoa e le khetho e ntle ka ho fetisisa lits'ebetsong tsa mocheso o phahameng haholo.
4. Ho hanyetsa ha kutu e ntle haholo. Limanete tsa Alnico ha li na ho bola 'me hangata li ka sebelisoa ntle le tšireletso ea bokaholimo
1. Ho bonolo ho demagnetize: Boholo ba eona bo tlase ba matla a ho qobella Hcb bo ka tlase ho 2 kOe ebe ho bonolo ho demagnetize tšimong e itseng e tlase ea demagnetizing, leha e sa sebetsoe ka hloko.
2. E thata ebile e brittle. E atisa ho phunya le ho petsoha.
1. Kaha coercivity ea Alnico magnets e tlaase, karo-karolelano ea bolelele ho bophara e lokela ho ba 5: 1 kapa ho feta e le hore u fumane sebaka se setle sa mosebetsi oa Alnico.
2. Ha Alnico makenete ba habonolo demagnetized ka ho tshwara bohlasoa, ho kgothaletswa ho etsa magnetizing ka mor'a kopano.
3. Limanete tsa Alnico li fana ka botsitso bo ikhethang ba mocheso. Sephetho se tsoang ho limatlase tsa Alnico se fapana hanyane ka liphetoho tsa mocheso, e leng khetho e nepahetseng bakeng sa lits'ebetso tse mamellang mocheso, joalo ka bongaka le sesole.
Ehlile ha re moetsi oa makenete oa Alnico, empa re litsebi tsa mefuta ea makenete ea limakete tse sa feleng ho kenyeletsoa Alnico. Ho feta moo, limmanete tsa rona tsa lefats'e tse sa tloaelehang tse hlahisoang le likopano tsa makenete li tla nolofalletsa bareki ho reka lihlahisoa tsa makenete ho rona ka mokhoa o bonolo.
