China Ring Bonded NdFeB Magnets Suppliers
Bonded NdFeB Magnets are manufactured by binding rapid-quenching NdFeB powder. The powder is mixed with resin to form a magnet by compression molding with epoxy or infection molding with nylon. The latter technique is particular effective in large volume production, though the magnetic value of products is lower than those made with compression molding because of their relatively lower density. Various shapes of high dimensional accuracy can be produced without further processing. Surface is treated by epoxy coating or nickel-plating to prevent corrosion

Other Properties of NdFeB Bonded 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, bonded ndfeb magnet
Advantages of Bonded Magnet
*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 Use 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. bonded magnet, bonded ndfeb magnet
*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. bonded magnet, bonded ndfeb magnet
A. With acid,alkali,organic solvent or electrolytes.
B. Immersed in water or in oil.
C. Space filled with hydrogen.
D. Space filled with corrosive gases such as Cl2,NH3,Nox,etc.
E. With radioactive rays.
