Neodymium hlau boron (NdFeB) hlau nplaum yog cov machinable heev thiab tuaj yeem ua rau ntau yam duab. Txhua lub hlau nplaum yog tsim thiab tsim raws li nws qhov kev siv thiab lub hom phiaj. Qhov tseeb lub zog ntawm cov hlau nplaum los ntawm cov khoom siv raw, thiab cov duab ntawm cov hlau nplaum cuam tshuam rau nws lub zog.
Feem ntau cov duab koj yuav pom yog square, round, spherical, thiab toroidal; Txawm li cas los xij, tsis muaj qhov txwv tsis pub muaj cov duab ntawm cov hlau nplaum. NdFeB arc hlau nplaum, NdFeB bar hlau nplaum, NdFeB square hlau nplaum, NdFeB cylindrical hlau nplaum, NdFeB disc hlau nplaum, nrog rau cov hlau nplaum toroidal, pyramidal hlau nplaum, conical hlau nplaum, daim duab peb sab prism hlau nplaum, lub plawv- cov hlau nplaum, thiab ntau dua.
