2.
Ferrite magnets include
sintered permanent magnets composed of Barium or Strontium Ferrite, and rubber/plastic
bonded magnets from injection molding or mold extrution.
3. Sintered ferrite magnet is 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.
