Permanent Magnet Ferrite Sintered At 1135℃ For Motorcycle Motors W021A
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 precision: Wet compression molding allows for the production of ceramic strontium ferrite magnets with high precision and uniformity, ensuring consistent performance and quality.
Complex shapes and sizes: This manufacturing process enables the creation of ceramic strontium ferrite magnets in a wide range of complex shapes and sizes, providing flexibility in design and applications.
Cost-effective: Wet compression molding is a cost-effective method for mass production of ceramic strontium ferrite magnets, making them a more economical choice for various industrial uses.
High magnetic properties: The resulting magnets have excellent magnetic properties, including high coercivity, remanence, and energy product, making them suitable for a range of demanding applications.
Durability and stability: Ceramic strontium ferrite magnets made by wet compression molding are highly durable and stable, with good resistance to corrosion and demagnetization, ensuring long-term performance and reliability.

Introduction Of Motercycle Motor:
Safety Features: Starter motors are designed with safety features to prevent damage due to prolonged engagement. These include an overrunning clutch mechanism that allows the pinion gear to disengage from the flywheel once the engine starts. This prevents the starter motor from over-speeding and potential damage.
Durability and Reliability: Automobile starting motors are designed to withstand the demanding conditions of engine cranking. They are built to be robust, durable, and resistant to heat, vibration, and contaminants present in the engine compartment.
