Neodymium Magnet

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.

  • Sintered NdFeB Magnets

    Produced by conventional powder metallurgy process. It still offers the strongest magnetic power nowadays and occupies an absolute predominance in the market share

  • Bonded NdFeB Magnets

    Composed of NdFeB powder and binder. Bonded NdFeB magnets can be further divided into compression molded and injection molded on the basis of binder type and molding process. It’s well-known for the complex shape, high dimensional precision, tight tolerance, integration capability with other functional parts, and the mass production capacity

Samarium Cobalt Magnet

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.

  • SmCo Magnets

    SmCo5 magnets' (BH)max values is regular between 14 and 24MGOe. SmCo5 is made of only Samarium and Cobalt and exhibit better corrosion resistance and machinability.

    Sm2Co17 magnets' (BH)max values is conventional between 22 and 32MGOe which much higher than the former SmCo5 series. Besides two basic elements Samarium and Cobalt, different grade of Sm2Co17 varies in the content of Iron (Fe), Copper (Cu), Zirconium (Zr).

AlNiCo 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.

  • Cast and Sintered AlNiCO Magnets

    Cast magnet is larger in density which provides it better magnetic performance. Casting process also well-suited to large and complex shapes.

    Sintered magnet exhibit slighter lower magnetic performance but better mechanical properties.

Ferrite Magnet

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.

  • Sintered Ferrite Magnets

    Sintered ferrite magnets are widely served for the various walks of life in the past several decades and still possess very large market share of permanent magnets now-days.

  • Bonded Ferrite Magnets

    Bonded ferrite magnets can be further classified to injection ferrite magnets, extruded ferrite magnets, and calendared ferrite magnets base on the binder type and molding process. The latter two magnets are collectively known as the rubber magnet.

Metal Injection Molding Product

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.

  • MIM Products

    Material Development of MIM Products including -

    • Soft Magnetic Alloy: FeSi3, FeCo 50/50

    • Special Alloy: Ti, W

    • Stainless Steel: 17-4PH, 316L, 420, 430, etc

Magnetic Assemblies

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.

  • Magnetic Motor Assemblies

    Permanent magnet excitation can significantly decrease power consumption and strengthen the running performance of the motor.Almost 2/3 of the rare earth PM are applied to make various kinds of PM motors nowadays. It’sprimarily composed of the rotor and stator. The rotor and stator act as the moving andstationary part in the PM motor, respectively. In addition to various motor magnets especiallylaminated magnet and radially oriented ringmagnet.

  • Halbach Array

    Halbach array was originally invented to help particle accelerators to focus beams. Magnetization direction of every two adjacent magnets in Halbach arrays differs on a specific angle, then magnetic field generated asymmetrical distribution. It can Generate a large and uniform magnetic field in a certain area. The field can even exceed the remanence of the PM material itself. 

    Enhance magnetic field on one side while keeping the field of the other side to very low level at the same time.

  • Plastic Integrated Magnet

    For plastic integrated magnet, multiple components can be integrated through the injection molding process even each component has its own property. Magnet embedded in the plastic could be undamaged under external impact, also be given excellent dimensional accuracy and superior cost advantage in the production of high quantity complex assemblies, thus capture customers from civilian use to automotive applications.

    There are insert molding, over molding, ultrasonic welding or some other options.
