Kev sib xyaw ntawm AlNiCo
Alnico hlau nplaumyog ib qho ntawm thawj tsim cov khoom siv hlau nplaum ruaj khov, yog cov hlau nplaum uas 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 1930. Ua ntej tsim cov khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb nyob rau xyoo 1960, aluminium-nickel-cobalt alloy yeej ib txwm yog cov khoom siv hlau nplaum ruaj khov tshaj plaws, tab sis vim muaj cov khoom siv ntawm cov hlau nplaum cobalt thiab npib tsib xee, ua rau cov nqi siab dua, nrog rau kev tshwm sim. ferrite ruaj khov hlau nplaum thiab tsis tshua muaj ntiaj teb cov hlau nplaum ruaj khov, cov ntaub ntawv txhuas-nickel-cobalt hauv ntau daim ntawv thov maj mam hloov. Txawm li cas los xij, hauv qee qhov kev siv kub thiab txiassiab sib nquskev ruaj ntseg yuav tsum tau, cov hlau nplaum tseem occupies ib tug unshakable txoj hauj lwm.
Alnico ntau lawm txheej txheem thiab hom
Alnico hlau nplaummuaj ob txheej txheem ntawm casting thiab sintering, thiab cov txheej txheem casting tuaj yeem ua tiav rau ntau qhov ntau thiab tsawg; Piv nrog rau cov txheej txheem casting, cov khoom sintered tsuas yog txwv rau qhov me me, qhov siab ntev ntawm qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob zoo dua.
Cov txheej txheem ntawm casting aluminium nickel cobalt yog batching → melting → casting → tshav kub kho → kev xeem → machining → soj ntsuam → ntim.
Sintered aluminium nickel cobalt yog tsim los ntawm hmoov metallurgy, cov txheej txheem ntau lawm yog batching → hmoov ua → nias → sintering → tshav kub kho → kev xeem → machining → tshuaj xyuas → ntim.
Kev ua haujlwm ntawm AlNiCo
Cov khoom lag luam nyob sib nqus flux ntom ntawm cov khoom siv no yog qhov siab, tab sis nws cov demagnetization yog qhov tsis muaj tseeb, thiab nws tus txiv neej tsis muaj tseeb nrog rau qhov demagnetization nkhaus, yog li kev saib xyuas tshwj xeeb yuav tsum tau them rau nws qhov tshwj xeeb thaum tsim thiab tsim hluav taws xob sib nqus ntawm lub cuab yeej. Cov hlau nplaum ruaj khov yuav tsum ruaj khov ua ntej. Rau ib qho piv txwv ntawm qhov nruab nrab anisotropic cam khwb cia AlNiCo alloy, muaj pes tsawg leeg ntawm Alnico-6 yog 8% Al, 16% Ni, 24% Co, 3% Cu, 1% Ti, thiab tus so yog Fe. Alnico-6 muaj BHmax ntawm 3.9 megagauss-oesteds (MG·Oe), coercivity ntawm 780 oersted, Curie kub ntawm 860 ° C, thiab siab tshaj plaws khiav hauj lwm kub ntawm 525 ° C. Raws li qhov qis coercivity ntawm Al-Ni-Co cov khoom siv hlau nplaum ruaj khov, nws yog nruj me ntsis txwv tsis pub tiv tauj nrog cov khoom siv ferromagnetic thaum siv, thiaj li tsis ua rau lub zos irreversible demagnetization los yog distortion ntawm.sib nqus fluxkev faib tawm ceev.
Tsis tas li ntawd, txhawm rau ntxiv dag zog rau nws qhov kev tiv thaiv demagnetization, qhov saum npoo ntawm Alnickel-cobalt ruaj khov hlau nplaum ncej feem ntau yog tsim los nrog cov kab ntev lossis cov rods ntev, vim tias cov khoom siv hlau nplaum annickel-cobalt ruaj khov muaj cov khoom siv tsis tshua muaj zog, siab hardness thiab brittleness, ua rau nyob rau hauv cov machinability tsis zoo, yog li nws tsis tuaj yeem tsim los ua cov txheej txheem, thiab tsuas yog me me ntawm kev sib tsoo lossis EDM tuaj yeem ua tiav, thiab forging thiab lwm yam khoom siv. kev ua haujlwm tsis tuaj yeem siv. Hangzhou Magnet Power Technology Co., Ltd. muaj qhov sib tsoo muaj peev xwm ntawm cov khoom no, kev ua haujlwm raug tuaj yeem tswj tau hauv +/- 0.005 hli, thiab muaj peev xwm tsim thiab ua cov khoom tshwj xeeb, txawm tias nws yog cov khoom siv los yog cov khoom tshwj xeeb tshwj xeeb zoo li cov khoom, peb tuaj yeem muab txoj kev tsim nyog thiab kev pab cuam.
Kev siv thaj chaw ntawm Alnico
Cam khwb cia txhuas-nickel-cobalt cov khoom siv tsuas yog siv rau hauv kev ntsuas, ntsuas cov hlau nplaum, cov khoom siv tsheb, cov suab nrov, cov khoom siv tub rog thiab aerospace thiab lwm yam. Sintered aluminium npib tsib xee cobalt yog tsim rau kev tsim cov complex, lub teeb, nyias, cov khoom me me, feem ntau yog siv hauv kev sib txuas lus hauv hluav taws xob, lub khob hlau nplaum ruaj khov, cov hlau nplaum hluav taws xob hloov pauv thiab ntau yam sensors Ntau yam kev lag luam thiab cov neeg siv khoom xav tau siv cov hlau nplaum ruaj khov, xws li motors, hluav taws xob guitar pickups, microphones, sensor hais lus, mus ncig yoj raj, (cowmagnet) thiab hais txog. Lawv txhua tus siv aluminium-nickel-cobalt hlau nplaum. Tab sis tam sim no, ntau yam khoom tau hloov pauv mus siv cov hlau nplaum tsawg hauv ntiaj teb, vim tias cov khoom siv no tuaj yeem ua rau muaj zog Br thiab siab dua BHmax, tso cai rau cov khoom ntim me me.
