Sintered neodymium iron boron magnets are the most commonly used type of permanent magnet material. It is made of alloys of neodymium, iron, and boron, forming a Nd2Fe14B tetragonal crystal structure. Meanwhile, according to its raw material composition, it is a rare earth magnet.

Customized sintered neodymium iron boron magnets are a complex process that includes the preparation, melting, grinding, pressing, sintering, machining, electroplating, magnetization, inspection, and packaging of formula powders.

Preparing the formula magnetic powder is the most important process. Because technicians can add additional rare earth elements to adjust magnetic properties, such as cobalt (Co) for high temperatures and dysprosium (Dy) for better intrinsic coercivity.
