Product Description

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 of other 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. In order to control the microstructure and the microchemistry so as to meet required performance, it also adds a small portion of other metal elements including aluminium (Al), copper (Cu), niobium (Nb), gallium (Ga), etc.
