What is bonded magnets

Bonded magnets refers to the magnetic powder with a certain permanent magnet performance and a certain proportion of binder mixed, according to a certain molding process made of a magnet. If the orientation magnetic field is applied in the molding process, so that the easy magnetization direction of magnetic powder in the magnet is along the same direction, this is an anisotropic bonded magnet, otherwise it is an isotropic magnet. There are a variety of forming methods for bonded magnets, including molding, injection molding, extrusion molding, and calendering.

Bonded magnets is a composite magnet with characteristics of permanent magnet and adhesive material, usually named after the type of magnetic powder or binder used. Widely used in industry to magnetic powder named with bonded ferrite, bonded aluminum nickel cobalt, bonded rare earth cobalt, bonded Ndfeb; The bonded magnets named by the adhesive are rubber magnets, plastic magnets, resin magnets, soft metal magnets and so on.
