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?
Low cost - Strontium ferrite is inexpensive and the wet molding process is relatively simple. This makes them cheaper than rare-earth magnets.
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 Fan Motor:
The fan motor is connected to an electrical power source, typically through a power cord. When the power is supplied to the motor, an electromagnetic field is generated within the motor.
The motor consists of two main components: the stator and the rotor. The stator is a stationary part of the motor and contains a set of electromagnetic coils. The rotor, on the other hand, is the rotating part of the motor and is attached to the fan blades.When the power is applied, an electric current flows through the coils in the stator, generating a magnetic field. The interaction between the magnetic field and the rotor creates a force that causes the rotor to rotate.
