Product Description

Ferrite magnet, otherwise referred as ceramic magnet, is developed by Japanese scholars Dr. Yogoro Kate and Dr. Takeshi Takei in 1930. As nonmetallic type of permanent magnetic material, ferrite magnet is utilizing iron oxide (Fe2O3), Barium Carbonate (BaCO3) or Strontium Carbonate (SrCO3) as raw material and then manufactured through ceramics process. Maximum operating temperature of sintered ferrite magnet can arrive 250 degrees Celsius. Sintered ferrite magnet also has superior corrosion resistance. Sintered ferrite magnet is generally used in various areas in the past several decades and its market share is still very large even the application range of sintered Neodymium magnets is more and more extensive. The most representative applications of sintered ferrite magnet include loudspeakers, permanent magnet (PM) motors and generators.
