Taw qhia:
AlNiCo yog cov khoom siv hlau nplaum tsim ua ntej tshaj plaws, uas yog cov hlau nplaum tsim los ntawm txhuas, npib tsib xee, cobalt, hlau, thiab lwm yam khoom siv hlau. AlNiCo cov khoom siv hlau nplaum ruaj khov tau ua tiav hauv xyoo 1930s. Thaum lub sij hawm ntawd, nws muaj qhov zoo tshaj plaws sib nqus kev ua tau zoo thiab me me kub coefficient, yog li nws tau siv dav hauv cov hlau nplaum ruaj khov. Tom qab xyoo 1960, nrog rau qhov kev vam meej ntawm ferrite mus tas li hlau nplaum thiab cov hlau nplaum tsis tshua muaj hauv ntiaj teb, daim ntawv thov ntawm AlNiCo cov hlau nplaum ruaj khov hauv cov motors tau maj mam hloov, thiab qhov kev faib ua feem pom qhov kev poob qis.
Permanent Magnet AlNiCo yog ib qho hlau alloy, ntxiv rau hlau, txhuas, npib tsib xee, cobalt, thiab lwm yam khoom me me uas txhim kho cov khoom sib nqus ntxiv.
AlNiCo alloys muaj lub siab coercivity thiab siab Curie kub. AlNiCo alloys yog tawv thiab nkig, tsis tuaj yeem ua haujlwm txias, thiab yuav tsum tau ua tiav los ntawm cov txheej txheem casting lossis sintering. AlNiCo tuaj yeem tsim cov teb sib nqus kom siab li 0.15 Tesla. Raws li ib qho piv txwv ntawm anisotropic cam khwb cia AlNiCo alloy nrog cov khoom nruab nrab, Alnico-6 yog tsim los ntawm 8% Al, 16% Ni, 24% Co, 3% Cu, 1% Ti, thiab tus so yog Fe. Qhov siab tshaj plaws lub zog khoom (BHmax) ntawm Alnico-6 yog 3.9 megagauss-oersteds (MG Oe), lub coercivity yog 780 oersted, Curie kub yog 860 ° C, thiab lub siab tshaj plaws khiav hauj lwm kub yog 525 ° C.
Hom:
Raws li cov txheej txheem ntau lawm, nws muab faib ua sintered AlNiCo thiab nrum AlNiCo. Cov duab ntawm cov khoom feem ntau yog puag ncig thiab square. Cov txheej txheem casting tuaj yeem ua tiav rau ntau qhov ntau thiab tsawg; piv nrog cov txheej txheem casting, cov khoom sintered yog txwv rau qhov me me, thiab qhov ntev ntev ntawm cov khoom tsim tawm yog zoo dua li ntawm cov khoom cam khwb cia dawb, thiab cov khoom sib nqus yog me ntsis qis dua cov khoom cam khwb cia, tab sis tuaj yeem ua tau zoo. zoo dua. Ntawm cov khoom siv hlau nplaum tas mus li, cam khwb cia AlNiCo cov hlau nplaum ruaj khov muaj qhov qis tshaj qhov kub thiab txias coefficient, thiab kev ua haujlwm kub tuaj yeem siab txog 600 degrees Celsius. AlNiCo cov khoom siv hlau nplaum ruaj khov yog siv dav hauv ntau yam ntsuas thiab lwm yam kev thov.
Daim ntawv thov:
Ntau cov khoom lag luam thiab cov neeg siv khoom xav tau cov hlau nplaum ruaj khov, xws li lub tshuab hluav taws xob, hluav taws xob guitar pickups, microphones, sensors, hais lus, mus ncig yoj raj, nyuj hlau nplaum, thiab lwm yam, txhua yam siv Alnico hlau nplaum. Tab sis tam sim no, ntau yam khoom tau hloov mus rau cov hlau nplaum uas tsis tshua muaj hauv ntiaj teb, vim tias cov ntaub ntawv no tuaj yeem muab cov khoom sib nqus muaj zog thiab cov khoom siv hluav taws xob ntau dua, tso cai rau cov khoom kom txo qhov loj me.
