Neodymium Magnets

Neodymium Iron Boron Magnets are made from rare earth raw materials and priced to be the most cost-effective high -energy magnets on the market.

Our standard NdFeB is rated to +80 deg C. We offer the whole range of Neodymium Iron Boron magnets, with Maximum Energy Product (BHmax) ratings from 33 MGOe to 52 MGOe (N33 to N52) and with a maximum operating temperature rating ranging from +80 deg C to +200 deg C (Grade N to EH)

Neodymium magnets are usually provided with a coating to protect against oxidizing.
Galvanic processed are used for metallic coating, like nickel, tin or zinc. Nickel-copper-nickel coatings or double coating are possible on request.

NdFeB magnets applied range: 
Acoustic: loudhailer, receiver, microphone, annunciator, sound stage, car audio etc. 
Electronics: watt-hour meter, water meter, noise meter,transducer etc,
Motor: VCM,CDDVD-ROM,dynamo, electromotor, servo motor, Pilot motors, motor, vibrator motor.
Machinery and equipment: magnetic separator, magnetic hanging
