Maalmahan, codsiyo badan Alnico waxaa lagu beddelay Neodymium ama Samarium Cobalt magnet. Si kastaba ha ahaatee, hantideeda sida xasilloonida heerkulka iyo heerkul aad u sarreeya ayaa ka dhigaya Alnico magnets lagama maarmaanka u ah suuqyada codsiyada qaarkood.
1. Birlab aad u sarreeya. Soo saarista hadhaaga ahi waxay ku badan tahay 11000 Gauss ku dhawaad la mid ah magnet Sm2Co17, ka dibna waxay soo saari kartaa dhul birlabeedka sare ee agagaarka.
2. Heerkulka shaqada oo sarreeya. Heerkulka ugu badan ee shaqada wuxuu noqon karaa mid sare ilaa 550⁰C.
3. Dejinta heerkulka sare: Magnets Alnico waxay leeyihiin isku-beegyada heerkulka ugu fiican ee walxo magnet ah. Magnet-ka Alnico waa in loo arkaa doorashada ugu fiican ee codsiyada heerkulka aadka u sarreeya.
4. Iska caabin daxalka heer sare ah. Magnets-ka Alnico uma nugul daxalka waxaana sida caadiga ah loo isticmaali karaa iyada oo aan wax ilaalin dusha ah laga ilaalin
1. Fudud in magnetization-ka laga saaro: Awoodeeda ugu badan ee qasabka ah ee hoose ee Hcb waxay ka hoosaysaa 2 kOe ka dibna way sahlan tahay in la demagnetize qaar ka mid ah meelaha hoose ee demagnetizing, xitaa aan si taxadar leh loo maareyn.
2. Adag oo jajaban. Waxay u nugul tahay jajabinta iyo dildilaaca.
1. Maaddaama isku-xidhka Alnico magnets uu hooseeyo, saamiga dhererka iyo dhexroorka waa inuu ahaadaa 5: 1 ama ka weyn si loo helo goob shaqo oo wanaagsan oo Alnico ah.
2. Sida Alnico magnets si fudud ayaa loo demagnetized by maaraynta taxadar la'aan, waxaa lagu talinayaa in la sameeyo magnetization ka dib kulanka.
3. Alnico magnets waxay bixiyaan xasilooni heerkul sare ah. Wax soo saarka Alnico magnets way ku kala duwan yihiin kuwa ugu yar ee isbeddelka heerkulka, taas oo ka dhigaysa doorasho ku habboon codsiyada heerkulka xasaasiga ah, sida caafimaadka iyo milatariga.
Dhab ahaantii ma nihin soo saaraha Alnico magnetka, laakiin waxaanu khabiir ku nahay noocyada birlabeedka joogtada ah oo ay ku jirto Alnico. Intaa waxaa dheer, magnets-ka dhulka naadirka ah ee aan iska soo saarnay iyo isu imaatinka magnetka ayaa u sahli doona macaamiisha inay si ku habboon noogu iibsadaan alaabta magnetka ah ee hal-joojin ah.
