Refrigerator Preservation Solution 840pcs Permanent Magnet Ferrite with Strontium Powder Composite

Ring Shaped Magnet Strontium Permanent Magnet Ferrites For Motorcycle Motor W4136A


What does Xinheng offer to customers?


Our company manufactures an-isotropic ceramic strontium ferrite magnet made by means of wet compression molding.


What's the feature of ceramic strontium ferrite magnet made by wet compression molding?

  • Composition - Contain strontium ferrite (SrFe12O19) as the primary magnetic material. Strontium ferrite has good magnetic properties and is inexpensive to produce.

  • Density - Have a high relative density of around 95% or more after sintering. This gives good mechanical strength.

  • An-isotropy - Exhibit strong magnetocrystalline an-isotropy due to their hexagonal crystal structure. This results in a preferred direction of magnetization along one axis.

  • Molding method - The powder is mixed with a liquid binder and compression molded into a dense green compact using high pressures. This orients the an-isotropic particles.

  • Firing process - The compact is then sintered at high temperature to develop density while preserving the induced magnetic anisotropy orientation from molding.

  • Remanence - Have a maximum magnetic flux density or remanence along the axis of anisotropy, but little/no remanence perpendicular to it.

  • Coercivity - Usually have medium to high coercivity depending on additives, density, and anisotropy level achieved.

The important role of permanent magnet ferrite in refrigerator:


Permanent magnet ferrite is a kind of material that can maintain its magnetism at room temperature, mainly composed of iron oxide and other metal oxides. The advantages of this material are its high magnetic energy product, good temperature resistance and stability, which is suitable for use in the complex environment of refrigerators. In the working mechanism of the refrigerator, the main role of permanent magnet ferrite is reflected in the drive of the compressor, the control of the switch and the sealing of the cold room door.

With the popularity of smart home appliances, the degree of intelligence and automation of refrigerators is constantly improving. Permanent magnet ferrite can not only be used for motors, but also as sensors and switching components to provide real-time monitoring and control functions for refrigerators. Through the combination of smart technology, the refrigerator can more effectively adjust the temperature, humidity, and even remote control through mobile phone applications, improving the user's convenience and experience.
