Kanda Alnico Magnet

Magineti eAlnico anowanzo kurongedzerwa nenhamba dzakapihwa neMagnetic Materials Producers Association (MMPA), semuenzaniso, alnico 3 kana alnico 5.

Alnico magineti anogadzirwa nekukandira kana sintering maitiro.[8] Anisotropic alnico magineti anotungamirwa nekudziya pamusoro pekupisa kwakanyanya uye kutonhora pamberi pemagineti. Ese ari maviri isotropic uye anisotropic alnico inoda kurapwa kwakaringana kupisa kuti igadzire yakakwana magineti zvivakwa-pasina iyo alnico's coercivity inosvika gumi Oe, inofananidzwa nesimbi yehunyanzvi, inova yakapfava magineti. Mushure mekupisa kupisa alnico inova chinhu chakaumbwa, chinodaidzwa kuti "mvura yekunaya" -ine iron- uye cobalt-rich[9] inonaya muhupfumi-NiAl matrix.

Alnico's anisotropy inotungamirwa padivi peinodiwa magineti axis nekushandisa ekunze magineti kwairi panguva yekunaya kwechikamu nucleation, inoitika kana kutonhora kubva 900 ° C (1,650 ° F) kusvika 800 ° C (1,470 ° F), padyo nenzvimbo yeCurie. . Pasina munda wekunze kune anisotropies emunharaunda yemaitiro akasiyana nekuda kwekuita magineti. Iyo precipitate chimiro "chipingamupinyi" chinopesana nekuchinja kwemagnetization, sezvo ichifarira mashoma magineti inoda simba rakawanda kuti iwane zvinhu mune chero nyika yepakati. Zvakare, isina simba remagineti inoshandura iyo magnetization yechikamu che matrix chete uye inodzorereka.

Alnico magineti akakodzera kune yakakwira tembiricha maapplication anosvika 550ºC
. Cast AlNICo Magnet yakanyatsogadzikana, ine yakanaka corrosion resistance uye yakajairwa kuoma kwe50 Rockwell C. Kana yangokandwa, zvinhu zvacho zvakaoma zvekuti machining chete anogoneka kugaya.
. Cast AlNICo Magnet inomiririra iyo inonyanya kushandiswa magineti zvinhu zviripo. Huwandu hwezvivakwa hunogona kugadzirwa nenzira kwayo kune chaiyo maapplication neshanduko kuongororo yechinhu uye kurapwa kwekupisa.
