Product Description


Neodymium Iron Boron (NdFeB) magnets are composed of Nd, Fe, B, Dy, Co and other minor elements. As the third generation of rare earth permanent magnet, NdFeB magnets become the most advanced commercialized permanent magnet material today. NdFeB magnets are available in both sintered and bonded forms.


Sintered NdFeB magnets have very high magnetic properties, excellent magnetic characteristics and good performance in ambient temperature. They are mechanically stronger than Sm-Co magnets and less brittle than ceramic & AlNiCo magnets. However, sintered NdFeB magnets are very easy to be corrosive. Therefore, for long time using, they have to be protected with special coating, such as Zn, Ni, Ni-Cu-Ni, or epoxy. In general, sintered NdFeB magnets need some finish machining to meet the final tolerance.


NdFeB magnets are produced at our two facilities in China, Ningbo and Baotou. High Energy materials are produced at our Baotou facility where we have installed the latest equipment and technology to produce the world's highest energy materials used in MRI, VCM, and other applications. Yunsheng serves the market with higher coercivity materials used in high performance motors, generators, sensors and other applications. We own the Patent License from Sumitomo Special Metals Co. for the manufacture and sales of Nd-Fe-B magnets. Our NdFeB magnets offer an excellent dollar value in terms of price/performance per unit of energy product allowing for smaller shapes and sizes with high magnetic performance. In addition, our low cost manufacturing resources will promote significant cost reduction for your application.

Testing Center

We are ISO/TS16949:2002 certified and well implement all procedures strictly under control. Problem preventive actions and quality assurance are preoperly combined with special inspection for all procedures from raw material purchasing ,outside cooperating part manufacturing,inside manufacturing to shipping . We also install a complete set of physical and chemical test equipment to make sure that all our products are manufactured and shipped under strictly quality control .

Salt Spray Test :

Mainly test the surface treatment against the corrosion.  Usually the tested samples will be  continuous sprayed 24 hours in the 35℃ temperature to see if there is any rust appearance on the surface. 

Projection Instrument:

Mainly test the magnets with irregular shapes such as arc segments and any other irregular-shaped parts to see if their dimensions meet the customers' requirements or not.  

PCT Instrument:

Mainly test the magnets to prevent against corrosion on the high temperature and high atmospheric pressure . Usually the test condition is 120℃ temperature and 2 atmospheric pressure .

Heat& Humidity Instrument:

Mainly test the magnet to against corrosion on certain temperature and humidity . Usually the test condition is 80℃ temperature and 90%+/-3% humidity

Hysteresgraph:

Mainly test the magnetic characteristics of the magnet, including Residual (Br ), Coercive(Hcb) . Intrinsic  Coercive(Hcj), Max. Energy product(BH max) and any other related magnetic parameters.
