What is a bonded magnet?

Bonded magnet is a kind of magnet made by mixing magnetic powder with a certain proportion of binder according to a certain molding process. If the orientation magnetic field is applied in the forming process, the easy magnetization direction of magnetic powder is in the same direction in the magnet, which is called anisotropic bonded magnet, otherwise it is isotropic magnet. There are various forming methods for bonded magnets, including molding, injection molding, extrusion molding and calendering.

Types of bonded magnets

Bonded ferrite, bonded aluminum nickel cobalt, bonded rare earth cobalt and bonded neodymium iron boron are widely used in industry; rubber magnet, plastic magnet, resin magnet and soft metal bonded magnet are named after the adhesive.

Characteristics of bonded magnets

Compared with sintered or cast magnets, the properties of bonded magnets are lower. The maximum magnetic energy product (BH) max of low-cost bonded barium ferrite is 3 kJ / M ~ 3, and that of bonded rare earth cobalt (2-17 type) is as high as 160 kJ / M ~ 3. It is easy to make magnets with high dimensional accuracy and complex shape or assembled parts by bonding process.

Application of bonded magnet

The bonded magnet is mainly used to make micro motor, stepping motor, magnetic seal ring and various toys.

China Bonded Magnet Manufacturer www.rizinia.com supplies bonded magnets, polymer bonded magnets, compression bonded neodymium magnets, injection molded ndfeb or ferrite magnets for scientific experiments or for industrial applications, in kinds of materials such as NdFeB/NIB/neodymium iron boron, etc.
This product is not a toy and is not to be used by children. This product is to be used for scientific experiments or for industrial applications. This product contains strong Neodymium magnet(s) that can be harmful or fatal if swallowed. Strong Neodymium magnets are fragile, they are brittle and will break or chip if they hit a hard surface or are snagged together. Always use the utmost care when handling Neodymium magnets.
