Brief: Discover our high-quality wet pressed processing permanent magnet ferrite designed for large fan motors in agriculture. These ceramic strontium ferrite magnets offer excellent magnetic properties, temperature stability, and corrosion resistance, making them ideal for demanding agricultural applications.
Related Product Features:
  • Composed of strontium ferrite (SrFe12O19) for good magnetic properties and cost-effectiveness.
  • High relative density of around 95% or more after sintering for superior mechanical strength.
  • Exhibits strong magnetocrystalline anisotropy due to hexagonal crystal structure.
  • Hexagonal platelet morphology of strontium ferrite powder enhances magnetic anisotropy.
  • Compression molded with high pressures to orient anisotropic particles for optimal performance.
  • Sintered at high temperature to develop density while preserving magnetic anisotropy.
  • High Curie temperature (450-470°C) ensures stability over a wide operating range.
  • Resistant to corrosion and suitable for mass production of complex geometries.
FAQ:
  • What are the key advantages of ceramic strontium ferrite magnets made by wet compression molding?
    These magnets are low-cost, temperature-stable, corrosion-resistant, and suitable for high-volume production, making them ideal for agricultural fan motors.
  • What is the maximum operating temperature of sintered ferrite magnets?
    Sintered ferrite magnets can operate at temperatures up to 350°C, with a Curie temperature of around 450°C.
  • How does the wet compression molding process benefit the magnets?
    The process orients the anisotropic particles during molding and sintering, resulting in high density and strong magnetic properties along the preferred axis.
