Summary

Ferrite magnet is a sintered product by powder metallurgy with the main component of oxidized steel, and the chemical form is XCo3 + 6Fe2O3, where Barium or Strontium is used for X. Depending on the processing method, either dry process using adhesive special powder or wet process is used, and magnet is categorized as isotropic or anisotropic based on the magnetic direction. Since stability is fairly high against temperature, and since the process is equivalent to it of powder metallurgy, complex feature may be fabricated through the mold. Unlike isotropic magnet, anisotropic magnet has much more active magnetic characteristics with pyro-synthesized ferromagnetic materials, and while isotropic magnet has weaker magnetic force, it is cheaper and is able to be manipulated arbitrarily.


Property

  Low cost.
  Comparatively stable against temperature, maximum energy (BH)max: 3~5 MGOe


Use

Speaker, Motor, Health Products, Tachometer, Speedometer, TV, Lead Switch, Clock Movement, etc.
