Alnico cov khoom siv hlau nplaum ruaj khov tsis tuaj yeem tsim los ua cov khoom siv vim yog cov yam ntxwv ntawm cov tshuab tsis muaj zog, siab hardness, brittleness, thiab machinability tsis zoo.Tsuas yog me ntsis kev sib tsoo lossis EDM tuaj yeem siv thaum lub sijhawm ua haujlwm, lwm txoj hauv kev xws li forging thiab lwm yam machining tsis tuaj yeem siv.
AlNiCo feem ntau yog tsim los ntawm txoj kev casting.Tsis tas li ntawd, hmoov metallurgy kuj tseem siv tau los ua cov hlau nplaum sintered, uas muaj kev ua haujlwm qis dua.Cam khwb cia AlNiCo tuaj yeem ua tiav rau hauv ntau qhov sib txawv thiab cov duab thaum sintered AlNiCo cov khoom yog qhov me me.Thiab cov khoom ua haujlwm ntawm sintered AlNiCo muaj qhov zoo dua qhov ntev, cov khoom sib nqus yog me ntsis qis tab sis lub tshuab ua haujlwm zoo dua.
Qhov kom zoo dua ntawm AlNiCo hlau nplaum yog siab remanence (txog 1.35T), tab sis qhov tsis txaus yog tias lub zog quab yuam yog tsawg heev (feem ntau tsawg dua 160kA / m), thiab demagnetization nkhaus yog tsis linear, yog li AlNiCo yog ib qho yooj yim rau cov hlau nplaum. yuav magnetized thiab kuj yooj yim rau demagnetized.Thaum sib nqus Circuit Court tsim thiab cov cuab yeej tsim khoom, tshwj xeeb yuav tsum tau them nyiaj thiab cov hlau nplaum yuav tsum ruaj khov ua ntej.Txhawm rau kom tsis txhob cuam tshuam ib nrab demagnetization lossis distortion ntawm magnetic flux density tis, nws yog nruj me ntsis txwv tsis pub tiv tauj nrog cov tshuaj ferromagnetic thaum siv.
Cam khwb cia AlNiCo cov hlau nplaum ruaj khov muaj qhov qis tshaj qhov kub thiab txias coefficient ntawm cov khoom siv hlau nplaum ruaj khov, kev ua haujlwm kub tuaj yeem ncav cuag 525 ° C, thiab Curie kub txog 860 ° C, uas yog cov khoom siv hlau nplaum ruaj khov nrog qhov siab tshaj plaws Curie point.Vim qhov kub thiab txias stability thiab kev laus stability, AlNiCo hlau nplaum tau zoo siv nyob rau hauv motors, instruments, electroacoustic li, thiab magnetic machinery, thiab lwm yam.
