1) Ndfeb disc magnet has superior magnetic properties than other magnets

2) Higher unit magnetic properties  

3) Smaller size and lighter weight in designing devices

4) Mostly an iron based alloy, NdFeB type rare earth magnet is much more prone to surface oxidation or rust, and elimination. Users should consider magnet coating, plating or suitable surface treatment

5) Less prone to chipping during handling

6) Lower temperature coefficient of magnetic properties than ceramic, higher than SmCo type rare earth magnet

7) Irreversible loss at high temperature

8) Types: 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, N48, and N50

9) High energy ranging from 8MGOe to 48MGOe with wonderful coercive force

10) Less expensive, and mechanically stronger and less brittle than SmCo

11) Density: 13%, smaller than SmCo products

12) For most applications, coating or plating is recommended

13) Advantages:

     a) High energy 

     b) Very high Hc and Hci output

     c) More economical than SmCo

     d) Wonderful performance at ambient temperature 

14) Disadvantages:

     a) Working temperature is below 2,000 C

     b) Prone to oxidation than other magnet alloys

15) Widely used in apparatus and instruments where a strong magnetic field is needed,

including motors, sensors, microphones, electro-acoustics,  magnetic separation,

magnetic suckers and magnetic therapy

We are specialized in producing NdFeB Magnet over many years,We guarantee the best price based on the same quality and service. Our finance conditiearon and industrial reputation are excellent.

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.
