Ferrite

Ferrite magnets are sintered permanant magnets composed of Barium or Strontium Ferrite this class of magnets aside from good resistance to demagnetisation, has the popular advantage of low cost.

Ferrite magnets are very hard and brittle, and require specialised machining techniques moreover, they should be machined in an unmagnetised state, we are equipped to machine these materials to specifications.

Anisotropic grades are oriented in the manufacturing direction, and must be magnetised in the direction of orientation, Isotropic grades are not oriented and can be magnetised in any direction, although some degree of greater magnetic strength will be found in any direction, although some degree of greater magnetic strength will be found in the pressing dimension, usually the shortest dimension.
