Brief: Join a quick walkthrough that focuses on what matters to users and operators. This video demonstrates the fine grinding process of our permanent ferrite magnet (R72.50mm-r60.7mm)×27.9mm, specifically designed for inverter motor W5018F. You'll see how we manufacture an-isotropic ceramic strontium ferrite magnets using wet compression molding and learn about their key advantages for industrial applications.
Related Product Features:
  • Manufactured using wet compression molding for precise particle orientation and high density.
  • Composed of strontium ferrite (SrFe12O19) as the primary magnetic material for cost-effectiveness.
  • Exhibits strong magnetocrystalline anisotropy due to hexagonal crystal structure.
  • Achieves high relative density of around 95% or more after sintering for excellent mechanical strength.
  • Maintains good magnetic properties over wide operating temperature ranges with high Curie temperature.
  • Offers dimensional consistency through compression molding for uniform magnet shapes.
  • Provides high coercivity values (700-1000 kA/m) without heavy rare earth elements.
  • Features excellent corrosion resistance as fully dense ceramic material.
Faqs:
  • What are the key advantages of using strontium ferrite magnets made by wet compression molding?
    These magnets offer low production costs, high magnetic properties with coercivities up to 700-1000 kA/m, excellent dimensional consistency, superior temperature stability with Curie temperatures around 450-470°C, and strong corrosion resistance as fully dense ceramic materials.
  • What applications are Xinheng's permanent ferrite magnets suitable for?
    Our magnets are widely used in automotive motors, inverter home appliances, fan motors, motorcycle motors, electrical tools, and various actuator motors including medical equipment and smart home devices.
  • What are the physical properties of sintered ferrite magnets?
    They feature a Curie temperature of 450°C, maximum operating temperature of 350°C, density of 4.8-5.0 g/cm³, hardness over Hv 530, and excellent temperature coefficients for Br and iHc, making them reliable for demanding applications.
