Permanent FERRITE Magnet


Permanent FERRITE Magnets

  • Pressed from approx. 80% iron oxide and 20% barium oxide or strontium oxide
  • Ground with diamond wheels
  • Inert to most environmental substances
  • Cheap raw material, therefore economic
  • Ceramic material, susceptible to impact or bending
  • Isotropic ferrite can be magnetised in any direction
  • Isotropic ferrite can be supplied to EN 71
  • Also available in plastic bonded version
  • Operating temperature range:- 40 °C up to + 200 °C
 
Regarding your query about the price of the magnetic materials, please use our specialised questionnaire.
As soon as we have all necessary information, we will send you a particular offer.
