Round Strong Permanent Sintered NdFeB Magnet

Round Strong Permanent Sintered NdFeB Magnet

The NdFeB Countersunk Magnet is very durable. It is coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth finish which greatly increase the longevity of the Magnets.
 
The ring magnets with holes are easy to mount with screws. They don't fall off. The heavy duty rare earth magnets can directly absorbed on magnetic material or can be fixed on non-magnetic material with screws (Included). Two ways to use to meet your various needs
 
Applications:
1. Electrical field: generators, motors, servo motors, micro-motors, motors, VCM, CD / DVD-ROM, vibration motors.
2. Electronics: permanent magnetic actuator vacuum circuit breakers, meter, sound meter, a reed switch, magnetic relays, sensors .
3. Machinery and equipment: magnetic separation, magnetic crane, magnetic machinery.
