Description

Manufacturer Neodymium Magnets

1. Materials: Nd-Fe-B

2. Shape: Various as you wish

3. Certificate: ISO 9001:2008 and ISO/TS 16949:2009

4. Powerful: Neodymium magnets (sintered NdFeB magnets) are more powerful than any other permanent magnet material in the market today.

5. Wide product range: N35-N50,35M-45M 33H-45H, 33SH-40SH, 30UH-38UH, 28EH-35EH.

6. High performance: High intrinsic coercive force (up to 35KOe) and energy product (up to 55MGOe), the maximum working temperature of 230 degrees Celsius.

7. Competitive price: Very competitive price (lower than market average) due to mass production.

8. Coating: All the neodymium magnets oxidize rapidly when exposed, so an anti-corrosive coating (usually electroplating) is used to extend their working life. Such as Ni, Zn, gold, copper, epoxy, chemical, parylene and so on;

9. Applications: Low/High-speed motor, Sensors, E-bike,Servo Motors, Equipment industry,car industry,
Wind generators, Loudspeakers, Stero ,Compass, Flashlight, Medical treatment equipment,Magnetic hooks, Magnetic holder, Magnetic therapy and so on;

10. Caution: You should be extremely careful when install neodymium magnet, as they can easily pinch fingers.

11. No for Kids: NdFeB magnets are not suitable for children
