Segment motor ferrite magnet

Ferrite magnets include sintered permanent magnets composed of   Barium or Strontium

Ferrite,and   rubber/plastic bonded ferrite magnets form injection molding or mold   extrution.
Sintered   ferrite magnets are very hard and brittle, and require specialized   machining techniques.
Moreover,they   should be machined in an unmagnetized state.We are equipped to machine these
materials   to specifications.






Rubber   bonded ferrite magnet is a permanet magnet composing of fine powder of   strontium ferrite,
synthetic   resin and additives.It can be processed ad a sheet,a roll or any kind of   shape and can be
coated to have magnetic characteristics or colors.As a matter of fact,it can be customized according
to the   requests of the customers,available in both anisotropic and isotropic grades.
