Sintered NdFeB magnets,i.e.sintered neodymium iron boron magnets, are those permanent magnetic materials that based on a Nd-Fe-B tetragonal crystal structure,and they are manufactured through a powder metallurgy (PM) process. They contain three basic elements neodymium, iron and boron.The neodymium element can be substituted by a portion ofother rare earth elements(REEs) including praseodymium(Pr), dysprosium(Dy),terbium(Tb), cerium(Ce), etc. The iron element can be substituted by a portion of cobalt (Co) element to increase the magnets'Curie temperature(Tc)thermal stability and corrosion resistance.Tiny Neodymium Disc Metal Magnetic Snap Fastener Neodymium magnets offer the highest (BH)max and high Hci(BH)max, the maximum energy product, of neodymium magnets is highest ofany kind of permanent magnets today in the world.(BH)max at different grades of neodymium magnets is 27 to 52MGOe.
