Product Description

neodymuim magnets, permanent rare earth neodymuim magnets,sintered permanent neodymuim magnets, ball neodymuim

1.Material: Sintered Neodymium-Iron-Boron.

2.Size: It will be different according to client's requirement;

3. Magnetic property: From N35 to N52, 35M to 50M, 35H t 48H, 33SH to 45SH, 30UH to 40UH, 30EH to 38EH;we are able to manufacture the full range of Sintered Nd-Fe-B products including the high energy magnets such as N52, 50M, 48H, 45SH, 40UH,38EH,34AH, (BH)max from 33-53MGOe, maximum working temperature up to 230 Degrees Centigrade.

4. Coating: Zn, Nickle, silver, gold, epoxy and so on.

5. Advantage:

a. Chemical Composition: Nd2Fe14B: Neodymium magnets are hard, brittle and easily corrode;

b. Moderate Temperature Stability: Neodymium magnets lose -0.09~-0.13%of Br/°C. Their working stability is under 80°C for low Hcj Neodymium magnets and above 200°C for high Hcj Neodymium magnets;

c. Excellet Strength Value: The highest(BH)max reaches up to 51MGOe;

6. Application: sensors, speakers, brushless motor, DC motor, Step motor, wind turbine/wind generator, magntic hooks, magnetic filter, cup magnet, Automobiles, magnetic coupling, magnetic chuch, permanent magnetic lift, and so on.

We always produce the magnet according to client's request.

We are China permanent rare earth magnet manufacturer offer best permanent rare earth magnet OEM, ODM,service.

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. 

 

HSMAG Magnets has been supplying high quality Neodymium Magnets to customers for about 20 years.

Super Magnet

Made of neodymium, the most powerful magnet material in the world
