Introduction to Basic Composition and Microstructure of Sintered NdFeB Magnet

Introduction to Basic Composition and Microstructure of Sintered NdFeB Magnet Sintered neodymium iron boron (NdFeB) magnet or neodymium (Nd) magnet, as its name implies, contains essential rare earth Nd element. Nd atoms, coupling with ferromagnetic element iron (Fe) atoms, help the magnet obtain high remanence (Br) and maximum energy product ((BH)max), which makes it extraordinary compared with other permanent magnets. In commercial sintered NdFeB magnet, Nd element is usually partially substituted by other rare earth elements including praseodymium (Pr), dysprosium… Read More
