Other Properties of Bonded NdFeB Magnets
Hybrid magnets to create different magnetic properties
With different ratio of additives to NdFeB powder, magnetic properties of hybrid NdFeB magnets can be tuned in a wide range. Once the ratio is fixed, magnetic property fluctuation can still be limited in a narrow bank. Hybrid magnets will meet customers’ specified properties.
Characteristics for the initial magnetization of NdFeB bonded magnets
Rapidly quenched NdFeB powder used for bonded magnets is multi grain with grain size of sub-micron. Powder is isotropic in magnetic properties, which results in flat increasing of remanence and intrinsic coercivity with applied field. Magnet can only be magnetized to saturation in high fields.
Bonded Magnet Advantages
Produced with high efficiency, stability and repeatability
Magnet and other part may form together in one step
Free choice of magnetizing direction-especially for multi-polar applications
High dimensional accuracy-large quantity applications with minimum post-press machining
Thin-wall ring and complex shape magnets
High resistance to corrosion

Safety Notes for the Application and Storage of Bonded Magnets
Do not place magnets near person wearing electrical medical equipment, such as pacemaker, because the magnet may result in malfunction of the equipment and endanger person’s life
Keep magnets away from magnetic memory media or other magnetic field sensitive devices such as magnetic cards, tapes, floppy disks, hard disk drivers and watches. Otherwise information stored in the media or the devices may be damaged
Big block of magnet will strongly attract each other or attract iron steel pieces,which may cause serious injure to person
Relatively weak in strength,bonded magnets may break into pieces when collide with other materials.Be careful in assembling magnets and prevent the finy fragments from entering into eyes or cause other injuries
Keep magnets in good condition and avoid following environment in case that magnets become rust or weaken in mechanical or magnetic strength

With acid, alkali, organic solvent or electrolytes
Immersed in water or in oil
Space filled with hydrogen
Space filled with corrosive gases such as Cl2, NH3, Nox, etc.
