Ferrite magnets are more commonly referred to as ceramic magnets. They are mostly composed of strontium and Iron oxide (SrO . 6Fe2O3) and offer solid performance with their low cost, higher coercive force than alnico and low recoil permeability. They are widely used for loudspeakers, small motors, generators, and rotors.
Proterial America offers a complete line of ceramic magnets.


  • Low cost
  • Strong resistance to corrosion
  • Easy to magnetize, thus allowing magnetization after assembly
  • Lower energy products than alnico or rare earth magnets
  • Very stable when exposed to temperature or stray fields
