Al - ni - co hlau nplaum: tus tiv thaiv kev kub ib puag ncig
Al - ni - co hlau nplaum yog ib qho ntawm cov ntxov tshaj plawsRuaj zog ferrite magnetCov ntaub ntawv, tsuas yog sau tau ntawm txhuas, npib tsib xee, cobalt thiab hlau. Nws qhov tseem ceeb tshaj plaws yog tias nws muaj qhov kub zoo heev, qis dua cov ntsuas kub uas tsis tshua muaj cua sov, thiab tuaj yeem ua haujlwm nyob rau hauv ib puag ncig kub siab tshaj plaws ntawm 600 degree. Nws yog cov khoom siv uas nyiam hauv aerospace, ntsuas kub thiab lwm thaj teb. Nyob rau hauv cov dav hlau tshuab thiab cov teeb meem kev taw qhia, al {4 4}} ni} co cov khoom sib xyaw ua haujlwm kom ntseeg tau tias cov khoom siv hauv siab. Tsis tas li ntawd, nws tau zoo machining kev ua tau zoo ua rau nws yuav tsum tau ua rau hauv cov duab nyuaj kom tau ntsib ntau yam kev xav tau. Txawm li cas los xij, nws cov khoom lag luam tsis tshua muaj zog txwv nws daim ntawv thov hauv scenes nrog cov kev xav tau siab heev rau kev sib nqus teb lub zog.
Ferrite tas mus li hlau nplaum: kev lag luam thiab cov khoom siv nrov nrov
Ferrite cov hlau nplaum tas mus li yog suav nrog hlau oxide, nrog cov ntsiab lus xws li barium thiab strontium ntxiv. Nws tau dhau los ua cov hlau nplaum tshaj plaws vim yog nws cov khoom siv raw ntau heev thiab tus nqi qis. Nws muaj kev sib tw siab, muaj zog anti - demagnetization muaj peev xwm, zoo corrosiater thiab rwb thaiv tsev, thiab tsis tas yuav muaj kev tiv thaiv nyuaj. Hauv lub neej txhua hnub, ferrite cov hlau nplaum ruaj khov yog dav siv nyob rau hauv tub yees qhov rooj tshuab raj, thiab hais lus hluav taws xob thiab mloog pob ntseg hauv cov khoom siv hluav taws xob. Hluav taws xob metres, cov dej me me, thiab cov motors me me hauv thaj chaw lag luam kuj cia siab rau lawv qhov kev ua tau ruaj khov. However, the low magnetic energy product makes it difficult to meet the high-end strong magnetic field requirements, and it is mainly used in the mid- and low-end markets.
Samarium cobalt tas zog magnet: kev sib xyaw ntawm kev ua haujlwm siab thiab siab ruaj khov
Samarium cobalt Tas nrho cov hlau nplaum yog qhov tsis tshua muaj lub ntiaj teb tas li magnet cov khoom muaj xws li Samarium thiab cobalt. Nws cov khoom sib nqus khoom tuaj yeem ncav cuag 14 {{{{{}} 28 degree, muaj kev ua haujlwm siab tshaj plaws ntawm ntau dua 350 cov khoom lag luam muaj zog ntau tshaj plaws ntawm kev kub siab. Nyob rau hauv daim teb ntawm aerospace, satellite cwj pwm tswj cov tshuab, dav hlau siab - kub sensors; Cov kev taw qhia cov lus qhia txog cov tshuab thiab cov chaw tsim hluav taws xob rau lub teb chaws tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv hauv tebchaws thiab cov tub rog; Raws li muaj kev lag luam siab - Cov khoom siv kho mob, yog txhua daim teb kho mob tau muab los ntawm Samarium cobalt cov hlau nplaum. Txawm li cas los xij, vim tus nqi siab ntawm cov ntaub ntawv raw muaj tsawg dua hauv av, nws yog feem ntau muaj cov kev xav tau zoo nrog kev xav tau kev ua tau zoo.
Neodymium hlau boron tas mus li magnet: "Sib Nqus King" ua kev lag luam niaj hnub
Raws li peb {{-}}}} Nplooj ntawv hlau nplaum Permanet yog hu ua "cov khoom sib nqus" nrog lub zog sib nqus ntawm ntau tshaj 50mgoe. Nws tuaj yeem tsim cov chaw sib nqus muaj zog nyob rau hauv ib qho ntim me me, pab rau cov miniaturize thiab lub teeb ci. Hauv thaj teb ntawm lub zog hluav taws xob tshiab, nws yog cov khoom siv tseem ceeb ntawm cov khoom siv tsav, txhim kho lub zog ua haujlwm ntawm lub tsheb; Hauv cov cua tshuab hluav taws xob, ndFebFerrite arc hlau nplaumDirect Drive Generator txhim kho lub zog tiam kev ua tau zoo; Cov neeg hais lus thiab kev co cov tshuab hluav taws xob ntawm cov khoom siv hluav taws xob xws li cov xov tooj txawb thiab cov khoos phis tawj tseem cia siab rau nws kom ua tiav kev ua tau zoo. Txawm li cas los xij, nws cursie kub yog tsawg (feem ntau 310-370 degree), thiab nws yooj yim rau oxidize, yog li nws xav tau cov kev kho kom zoo nkauj.
