Phosa i-Alnico Magnet

Imagnethi yeAlnico ngokwesiko ihlelwa kusetyenziswa amanani anikezelwe nguMbutho wabavelisi beMagnetic Materials (MMPA), umzekelo, i-alnico 3 okanye i-alnico 5.

Imagnethi yeAlnico iveliswa ngokujula okanye ngeenkqubo zokucoca.[8] Iimagnethi ze-alnico ze-Anisotropic zijoliswe ngokufudumeza ngaphezu kobushushu obubalulekileyo kunye nokupholisa kubukho bemagnethi. Zombini i-isotropic kunye ne-anisotropic alnico zifuna unyango olufanelekileyo lobushushu ukuphuhlisa iimpawu zemagneti ezifanelekileyo-ngaphandle kokunyanzeliswa kwe-alnico malunga ne-10 Oe, xa kuthelekiswa nentsimbi yobugcisa, into ethambileyo yamagnetic. Emva kokuba i-alnico yonyango lobushushu iba yinto edibeneyo, ebizwa ngokuba "izinto zemvula"-iqulethe i-iron- kunye ne-cobalt-rich [9] imvula kwi-matrix ecebileyo ye-NiAl.

I-Alnico's anisotropy ijongiswe ecaleni kwe-axis yemagnethi efunwayo ngokufaka i-axis yangaphandle yemagnethi kuyo ngexesha le-nucleation yamasuntswana, eyenzeka xa kuphola ukusuka kwi-900 °C (1,650 °F) ukuya kuma-800 °C (1,470 °F), kufutshane nendawo yeCurie. . Ngaphandle kwentsimi yangaphandle kukho i-anisotropies yendawo yee-orientation ezahlukeneyo ngenxa ye-magnetization ezenzekelayo. Ubume bemvula "sisithintelo" ngokuchasene notshintsho lwemagneti, njengoko ikhetha iindawo ezimbalwa zemagneti ezifuna amandla amaninzi ukufumana imathiriyeli kulo naliphi na ilizwe eliphakathi. Kwakhona, indawo enemagnethi ebuthathaka itshintsha imagneti yesigaba sematrix kuphela kwaye iyabuyiswa.

Iimagnethi zeAlnico zilungele ukusetyenziswa kobushushu obuphezulu ukuya kuthi ga kwi-550ºC
. I-Cast AlNICo Magnet izinzile kakhulu, inokumelana ne-corrosion elungileyo kunye nobulukhuni obuqhelekileyo be-50 Rockwell C. Xa iphoswe, izinto ezilukhuni zinzima kakhulu ukuba machining kuphela enokwenzeka kukugaya.
. I-Cast AlNICo Magnet imele eyona mathiriyeli yemagnethi iguquguqukayo ekhoyo. Uluhlu lweepropati lunokuthi lwenziwe ngokuchanekileyo kwizicelo ezithile ngotshintsho kuhlalutyo lwento kunye nonyango lobushushu.
