Cov hlau nplaum tas mus li AlNiCo yog cov hlau nplaum uas muaj txhuas, npib tsib xee, cobalt, thiab lwm yam khoom siv hlau nplaum ntxiv ntxiv rau cov hlau.AlNiCo alloy muaj siab coercivity thiab siab Curie kub. AlNiCo nplhaib hlau nplaum yog tawv 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 nplhaib hlau nplaum muaj qhov zoo ntawm siab remanence (txog 1.35T), qis coercivity (feem ntau tsawg dua 160kA / m) thiab nonlinear demagnetization nkhaus, yog li AlNiCo nplhaib 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 nplhaib hlau nplaum muaj qhov qis tshaj qhov kub thiab txias coefficient. AlNiCo nplhaib hlau nplaum muaj qhov kub thiab txias stability, thiab yog tsim rau kev ua cov twj paj nruag, motors, electroacoustic li, magnetic machinery, thiab lwm yam.
Qhov zoo thiab qhov tsis zoo ntawm AlNiCo Magnets
Qhov zoo
• Cam khwb cia Alnico muaj ib tug ze net zoo li. Cam khwb cia alnico tuaj yeem ua rau cov duab nyuaj nrog cov qauv sib nqus.
• Alnico Br siab li NdFeB ntawm chav tsev kub.
• Yuav siv tau txog li 450-550 degrees C (842-932F).
• Tsawg kawg variation nyob rau hauv magnetic output nrog kub hloov ntawm tej khoom sib nqus.
• Muaj peev xwm muab pov rau hauv qhov loj heev.
Qhov tsis zoo
• Sintered AlNiCo feem ntau yog txwv rau qhov me me mus rau qhov nruab nrab thiab cov duab yooj yim dua.
• Tsawg coercivity (Hcj) ua rau lawv yooj yim demagnetise.
• Complex cam khwb cia alnico qee zaum xav tau xuab zeb pwm tooling uas yuav kim yog tias tsis muaj cov cuab yeej uas twb muaj lawm.
