2. 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.
3. Rubber bonded ferrite magnet is a permanent magnet composing of fine powder of strontiumferrite, synthetic resin and additives.
This magnet was widely used many different fields in many years.
4. It can be processed as a sheet, a roll or any kind of shaped 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.Ferrite disc magnets used in magnetic holding systems, crafts, magnetic toy and so on.
