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.

  • Particle shape - The strontium ferrite powder used typically has a hexagonal platelet morphology which helps promote magnetic an-isotropy during molding and sintering.

  • 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.

 

 

What's the key advantages of ceramic strontium ferrite magnets made by wet compression molding?

  • High magnetic property-Even without heavy rare earth element additions, strontium ferrite magnets can achieve coercivities of 700-1000 kA/m, making them suitable for many applications.

  • Dimensional consistency - The compression molding process allows for close dimensional tolerances and uniform magnet shapes to be produced consistently.

  • Temperature stability - Strontium ferrite magnets have high Curie temperatures, typically around 450-470°C. They maintain good magnetic properties over a wide operating temperature range.

  • Resistance to corrosion - Being fully dense ceramic materials, they are not prone to corrosion like bonded magnets containing additives.

  • Mass production capability - The molding process is amenable to automated high-volume manufacturing of complex magnet geometries.​​

Introduction Of Universal Motor:

The motor mainly consists of an electromagnet winding or distributed stator winding to generate a magnetic field and a rotating armature or rotor and other accessories. Under the action of rotating magnetic field of the stator winding, the current passes through the armature squirrel cage aluminum frame and is made to rotate by the action of magnetic field.
