    NdFeB magnets can be manufactured by sintering, compression bonding, injection molding, and extrusion. The sintered form holds the highest energy product of up to 48MGOe, while the bonded form holds a lower energy product of up to 10MGOe. The majorities of NdFeB magnets are anisotropic and can only be magnetized in the orientation direction. In general, magnetizing fields of approximately 30KOe are required to saturate NdFeB magnets.

    The sintered NdFeB magnet is an alloy magnet that is mainly composed of Neodymium, Iron, boron and other microelements (Dy、Al、Nb、Mo、Co and so on). By powder metallurgy process, the melted alloy can be made into powder. The powder will be oriented in magnetic field and then be shaped. Finally it will be compacted after sintered in the inert gas or vacuum. So Sintered NdFeB has very high energy, coercive force, and cost performance, also good mechanical feature. It is known as “King of magnet”.
