NdFeB magnet is the most powerful and commonly used rare earth magnet. 

Neodymium magnets are primary made from an alloy of Neodymium (Nd), Iron (Fe), and Boron (B) to form the Nd2Fe14B main phase which has excellent magnetic properties. In addition, Neodymium resources comparatively rich. The successful deveopment of Neodymium magnet declared the birth of the third-generation rare earth permanent magnet. Since then, Neodymium magnets are served for nearly all industries.

Samarium Cobalt magnet, also referred to as SmCo magnet, is produced by traditional powder metallurgy process and can be classified into SmCo5 based and Sm2Co17 based according to alloy composition. SmCo5 and Sm2Co17 are normally referred as the 1st and 2nd generation of rare earth permanent magnetic material, respectively.

Sintered NdFeB magnets ruled rare earth PM market since its inception, therefore, SmCo magnet is marginalized seriously as a result of relatively lower magnetic properties, complex processing technologies, and costs. But in reality, it is still playing an irreplaceable role in high-temperature applications which are not possible for sintered NdFeB magnet.

AlNiCo as a member of non-rare earth metallic permanent magnetic material, once ruled the PM industry before the rare earth PM was emerged. 

Besides commonly used in loudspeaker, sensor, guitar pickup, magnetic chuck, or magnetic lifter, it is still serving for some specialty application owing to its matchless temperature stability. It can be made via either casting or sintering. The grades mainly vary in Cobalt content and relevant heat treatment process. This historical magnet can be further divided to isotropic or anisotropic and grain oriented or nonoriented.

Ferrite magnets can be divided into sintered ferrite magnets and bonded ferrite magnets according to the manufacturing process. Sintered and bonded form has their distinctive magnetic performance and application scope. Ferrite magnet, otherwise referred as ceramic magnet or hard ferrite, as nonmetallic type of permanent magnetic material, is utilizing iron oxide (Fe2O3), Barium Carbonate (BaCO3) or Strontium.

Carbonate (SrCO3) as raw material. Strontium ferrite magnets and Barium ferrite magnets are also known as anisotropic and isotropic ferrite magnets, respectively. In addition to superior cost advantage and corrosion resistance, ferrite magnets are medium in magnetic properties and can be applied under relatively high temperature conditions.

MIM is a metalworking process in which finely powdered metal is combined with binder material to create a “feedback” that is then shaped and solidified using injection molding. The molding process allows high volume, complex parts to be shaped in a single step. After molding, part undergoes conditioning operations to remove the binder (debinding) and densify the powders. The MIM finished products are miniature components used in many industries and applications.

Magnetic assemblies refer to the tool or system which incorporates permanent magnetic material and different kind of non-magnetic together, then to meet the purpose of getting much stronger holding to the ferromagnetic load or obtaining an ideal magnetic field in specific space owing to the presence of the magnetic circuit.

Advantages of magnetic assemblies is to enhance Mechanical and Magnetic strength, and non-magnetic parts typically have the incorporate mechanisms for different holding applications.
