Bonded Ndfeb Magnets - China

price: contact company for price

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.

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 customer's specified properties.

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.

Advantages of Bonded Magnets

*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.
