Bonded Magnet Materials and Processing Options

Bonded Magnet Materials and Processing Options Bonded magnets are an important but often overlooked group of products that magnetic circuit and device designers should consider when choosing the optimum permanent magnet type for their specific application need. In their most basic form bonded magnets consist of two components; a hard magnetic powder and a non-magnetic [...]

Isotropic polymer bonded NdFeB magnets

Isotropic polymer bonded NdFeB magnets - The raw material powder is manufactured by rapid quenching of prescribed alloys into nanocristalline flakes which are subsequently annealed for optimum magnetic properties. Shortly after the invention of rapidly quenched NdFeB magnet powders, MPCO had started to develop polymer bonded magnets from these powders. Isotropic polymer bonded NdFeB [...]

What Are Bonded Magnets Anyway?

What Are Bonded Magnets Anyway? • Bonded magnets are composites of a permanent magnetic powder(s) embedded in a non‐magnetic matrix. • The matrix is typically a thermoplastic or elastomeric binder. • Common processing techniques are extrusion, injection molding, compression bonding, and calendering. • Exhibit excellent mechanical properties compared to fully dense rare earth and ferrite magnets. • End product has good finish and dimensional tolerances requiring no finishing operations. • Injection molded magnets can be formed into complex shapes and be insert or over molded directly onto other components to produce assemblies. • The non‐magnetic binder lowers the density of the magnet and dilutes the contribution of the magnetic powder. • They generate less magnetic output per unit volume than fully dense magnets. • The two most common magnetic powders are isotropic NdFeB and hard ferrite.
