Detailed Product Description

Ndfeb neodymium-iron-boron magnet

As a manufacturer of ndfeb permanent magnet for over ten years in China, the annual capacity of production has reached to 600mts,90% of them are exported to many customers around the world, including those final users and trader agents. We have been certificated by iso9002, the product quality is in good control and the company running well. Good quality, competitive price, satisfied service, those are always supplied to every client in the business with us. Any request in material. Shapes, size of the permanent magnets product is welcome and will be solved by our technologist.



Supported by our sophisticated quality system, we can supply top-quality ndfeb magnets for our worldwide customers.

Ndfeb(neodymium-iron-boron) magnet is used most popular by people in industry
And our daily life, because it has superior magnetic properties than other kind of magnets.
The outstanding characteristics are as follows--------

*higher unit magnetic properties than other magnet and assure you of smaller size and lighter weight in designing devices.

*being mostly an iron based alloy, ndfeb type rare earth magnet is much more prone to surface
Oxidation or rust. To eliminate such a problem, the user should consider magnet coating, plating, or suitable surface treatment.

*being less prone to chipping during handing

*lower temperature coefficient of magnetic properties than ceramic but higher than smco type rare earth magnet.
Therefore, this ndfeb type rare earth magnet will suffer irreversible loss at high temperature.


We can produce and supply following items:
N30, n33, n35, n38, n40, n42
N30m, n33m, n35m, n38m, n40m
N27h, n30h, n33h, n35h, n37h
N27sh, n30sh, n33sh, n35sh
N25uh, n28uh, n30uh n35sh, n38. N45.....


Advantages for using ndfeb:

High energy for size
Very high hc and HCI output
More economical than smco
Wonderful performance in ambient temperature situations

Disadvantages:
Working temperature is below 2000c
It's prone to oxidation than any other magnet alloy.

Ndfeb (neodymium-iron-boron) magnets are now widely used in apparatus and instruments where a strong magnetic field is needed, such as motors, sensors, microphone. Electro-acoustics, magnetic seperation, magnetic suckers and magnetic therapy, etc..
