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

  • High magnetic performance: The Strontium Ferrite (SrFe12O19) material used in these magnets offers strong magnetic properties, making them suitable for a wide range of applications.

  • Flexibility in design: Wet compression molding allows for the creation of magnets in various shapes and sizes, offering design flexibility to meet specific requirements.

  • Cost-effective production: The wet compression molding process enables efficient and cost-effective production of ceramic strontium ferrite magnets, making them a practical choice for large-scale manufacturing.

  • Good temperature stability: These magnets exhibit stable performance over a wide temperature range, making them suitable for use in high-temperature applications.

  • Resistance to corrosion: Ceramic strontium ferrite magnets are highly resistant to corrosion, making them suitable for use in harsh environments.

  • Low manufacturing waste: The wet compression molding process minimizes material waste, making it an environmentally friendly manufacturing method.

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:

Starter Motor: Permanent magnet ferrites find application in the starter motor of motorcycles. The starter motor is responsible for starting the engine by cranking it until it reaches the necessary speed for combustion. Ferrite magnets provide the required magnetic field strength for the starter motor's operation, allowing reliable and efficient engine starts.
