Products are widely used in the information industry, defense industry, automobile industry, household appliances, instrumentation, medical equipment and magnetic machinery and other fields of national economy.
Bonded Neodymium magnets are made of the powerful Nd-Fe-B material mixed into an epoxy binder. The mix is appropriately 97 vol% magnet material to 3 vol% epoxy. The manufacturing process involves combining Nd-Fe-B powder with an epoxy binder and compressing the mixture in a press and curing the part in an oven. Permanent Radiation Oriented Ring Magnets
Powerful Bonded Nd-Fe-B Cylindrical Ring Magnet
Advantages:
1.Produced with high efficiency, stability and repeatability.
