Cov hlau nplaum tas mus li AlNiCo yog ib qho hlau ntawm cov hlau uas txhuas, npib tsib xee, cobalt, thiab lwm yam khoom siv hlau nplaum me me ntxiv ntxiv rau cov hlau.AlNiCo alloy muaj kev coercivity siab thiab kub Curie kub. AlNiCo disc hlau nplaum yog ib qho nyuaj thiab nkig thiab tsis tuaj yeem ua haujlwm txias. Nws yuav tsum tau ua los ntawm casting los yog sintering txheej txheem. AlNiCo tuaj yeem tsim qhov chaw sib nqus mus txog 0.15 Tesla. Rau ib qho piv txwv ntawm qhov nruab nrab anisotropic cam khwb cia Al nickelco alloy, muaj pes tsawg leeg ntawm AlNiCo-6 yog 8 feem pua Al, 16 feem pua Ni, 24 feem pua Co, 3 feem pua Cu, 1 feem pua 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 degree, thiab ib tug siab tshaj plaws khiav hauj lwm kub ntawm 525 degree .Ua ntej lub discovery ntawm Cov hlau nplaum tsis tshua muaj hauv ntiaj teb nyob rau xyoo 1970, AlNiCo yog cov khoom siv zoo tshaj plaws rau cov hlau nplaum ruaj khov.

AlNiCo disc hlau nplaum muaj qhov zoo ntawm qhov siab remanence (txog 1.35T), qis coercivity (feem ntau tsawg dua 160kA / m) thiab nonlinear demagnetization nkhaus, yog li AlNiCo disc hlau nplaum yog ib qho yooj yim rau magnetized, tab sis kuj yooj yim rau demagnetize. Kev saib xyuas tshwj xeeb yuav tsum tau them rau nws qhov tshwj xeeb hauv kev tsim thiab tsim cov khoom sib nqus ntawm cov khoom siv, thiab cov hlau nplaum yuav tsum ruaj khov ua ntej. 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 flux ceev tis.

Ntawm tag nrho cov khoom siv hlau nplaum ruaj khov, AlNiCo disc hlau nplaum muaj qhov qis tshaj qhov kub thiab txias coefficient. AlNiCo disc magnet muaj qhov kub thiab txias stability thiab kev laus stability, thiab yog haum rau ua cov twj paj nruag, motors, electroacoustic li, magnetic machinery, thiab lwm yam.

Yam ntxwv

AlNiCo disc hlau nplaum muaj nyob rau hauv cam khwb cia thiab sintered daim ntawv. Feem ntau siv rau hauv cov ntawv thov uas qhov ntsuas kub ruaj khov yog qhov tseem ceeb, AlNiCo hlau nplaum nthuav tawm siab Br, tab sis qis Hc, thiab BHmax hauv 5 MGOe ntau yam. Lawv yog cov hlau nplaum ruaj khov tshaj plaws ntawm txhua hom hlau nplaum, thiab tuaj yeem siv tsis muaj qhov poob loj txog li 500⁰C. Lawv kuj yooj yim demagnetized, tiv taus oxidation zoo. Cov khoom siv hluav taws xob sib txawv ntawm 1.4 MGOe txog li 7.5 MGOe.

Feem ntau ntawm AlNiCo hlau nplaum qib yog anisotropic (lawv tsuas tuaj yeem sib nqus hauv ib qho axis / kev taw qhia) - lawv yog cov qib hlau nplaum muaj zog dua ntawm Alnico. Lwm tus yog isotropic (lawv tuaj yeem sib nqus hauv txhua qhov kev taw qhia lossis cov lus qhia) - lawv tsis muaj zog tab sis muaj ntau tus qauv tsim thiab kev ua haujlwm yooj yim.

Daim ntawv thov

AlNiCo disc hlau nplaum yog siv rau ntau yam kev siv, tshwj xeeb tshaj yog cov uas yuav tsum tau muaj peev xwm tiv taus kev khiav hauj lwm kub txog li 1, 000⁰F (540⁰C). Los ntawm kev sib piv, samarium cobalt hlau nplaum tuaj yeem ua haujlwm txog li 600⁰F (315⁰C), thaum cov hlau nplaum neodymium raug txwv rau kwv yees. 428⁰F (220⁰C).
