Niaj hnub no, hauv ntau daim ntawv thov Alnico tau hloov los ntawm Neodymium lossis Samarium Cobalt hlau nplaum. Txawm li cas los xij, nws cov cuab yeej zoo li qhov kub thiab txias thiab ua haujlwm kub ua rau Alnico hlau nplaum indispensable nyob rau hauv tej daim ntawv thov kev lag luam.
1. High magnetic teb. Residual induction yog siab rau 11000 Gauss yuav luag zoo ib yam li Sm2Co17 hlau nplaum, thiab tom qab ntawd nws tuaj yeem tsim cov hlau nplaum siab nyob ib puag ncig.
2. Ua haujlwm kub. Nws qhov siab tshaj plaws ua haujlwm kub tuaj yeem siab txog 550 ⁰C.
3. Kub kub stability: Alnico hlau nplaum muaj qhov zoo tshaj plaws kub coefficients ntawm tej khoom hlau nplaum. Alnico hlau nplaum yuav tsum raug suav hais tias yog qhov kev xaiv zoo tshaj plaws hauv kev siv kub heev.
4. Zoo heev corrosion kuj. Cov hlau nplaum Alnico tsis tuaj yeem ua rau corrosion thiab feem ntau tuaj yeem siv yam tsis muaj kev tiv thaiv saum npoo
1. Yooj yim rau demagnetize: Nws qhov siab tshaj plaws qis coercive quab yuam Hcb qis dua 2 kOe thiab tom qab ntawd nws yooj yim rau demagnetize hauv qee qhov qis demagnetizing teb, txawm tias tsis muaj kev saib xyuas.
2. Nyuaj thiab nkig. Nws yooj yim rau chipping thiab cracking.
1. Raws li cov coercivity ntawm Alnico hlau nplaum yog tsawg, qhov piv ntawm qhov ntev mus rau txoj kab uas hla yuav tsum yog 5: 1 los yog loj dua thiaj li yuav tau ib tug zoo ua hauj lwm point ntawm Alnico.
2. Raws li Alnico hlau nplaum yog yooj yim demagnetized los ntawm careless tuav, nws yog pom zoo kom ua lub magnetizing tom qab sib dhos.
3. Alnico hlau nplaum muab qhov kub thiab txias stability. Cov zis los ntawm Alnico hlau nplaum sib txawv tsawg kawg nrog kev hloov pauv ntawm qhov kub thiab txias, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv kub, xws li kev kho mob thiab tub rog.
Tseeb tiag peb tsis yog Alnico hlau nplaum chaw tsim tshuaj paus, tab sis peb yog ib tug kws tshaj lij nyob rau hauv magnetic hom ntawm cov hlau nplaum ruaj khov nrog rau Alnico. Ntxiv mus, peb tus kheej tsim cov hlau nplaum tsis tshua muaj hauv ntiaj teb thiab cov hlau nplaum sib nqus yuav ua rau cov neeg siv khoom muaj kev yuav khoom ntawm cov khoom siv hlau nplaum los ntawm peb yooj yim.
