NdFeB hlau nplaum yog tsim los ntawm neodymium (Nd), hlau (Fe), thiab boron (B).Lawv yog tsim los ntawm ib tug hmoov metallurgy txheej txheem, nyob rau hauv cov ntaub ntawv raw yog melted, cam khwb cia rau hauv ingots, crushed rau hauv me me hais, thiab ces nias rau hauv lub siab xav.NdFeB hlau nplaum muaj lub zog ceev ceev, uas txhais tau hais tias lawv tuaj yeem khaws ntau lub zog sib nqus hauv ib lub ntim me me.Lawv kuj muaj cov khoom sib nqus zoo heev, xws li kev coercivity siab (lub peev xwm los tiv thaiv demagnetization), siab remanence (muaj peev xwm khaws cov hlau nplaum tom qab sab nraud magnetic teb raug tshem tawm), thiab siab sib nqus flux ceev (tus nqi ntawm magnetic flux ib cheeb tsam. ).
