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 Motercycle Motor:
Motorcycle motor is the power source of motorcycle, which uses electric energy to convert into mechanical energy to drive the motorcycle forward. The working principle of the motorcycle motor is to generate a magnetic field through the current, and the force generated by the magnetic field and current makes the rotor of the motorcycle motor rotate, thereby driving the motorcycle forward.
Motorcycle motor mainly includes two parts: stator and rotor. The stator is a fixed part, usually consisting of a set of windings and an iron core. When an electric current passes through the winding, a magnetic field is created. The rotor is the rotating part, which is also rotated by a magnetic field generated by an electric current.
Motorcycle motor adopts the working principle of DC motor or AC motor. In a DC motor, the current generated by the DC power supply applied to the stator forms a magnetic field in the winding, which causes the rotor to be rotated by the electromagnetic force. In the AC motor, through the stator and rotor magnetic field interaction, through the stator and rotor magnetic field interaction to produce rotating force.
