General Descriptions of sintered NdFeB magnets
The most powerful magnets available, Sintered NdFeB is produced by powder metallurgical process with chemical composition of Nd2Fe14B, which are hard, brittle and easily corrode, involving the sintering of compacts under vacuum. Poorest corrosion resistance of all commercial magnetic material. Grinding and slicing possible; very reactive with moisture and oxygen; coating may be applied depending on the expected environment. The sintered NdFeB magnet has high remanence, high coercive force, high-energy product and high ratio between performance value and product cost. It may be easily formed into various sizes. The intrinsic coercive force is over 30,000 Oe. Neodymium magnets lose -0.09 ~ -0.13% of Br/°C. Their working stability is under 80°C for low Hci. Neodymium magnets and above 200°C for high Hci Neodymium magnets. The highest (BH)max reaches up to 51MGOe . The choice of Strip casting and HDDR technology in our factory allows us to make high performance NdFeB over N52 possible. Surface treatments have been developed that allow the sintered NdFeB magnet to be used in most applications. The treatments include gold, nickel, zinc and tin plating and epoxy resin coating.
Features of Sintered NdFeB Magnet:
1. Moderate temperature stability; Extremely resistance to demagnetization.
2. Excellent strength value.
3. Advanced Technology.
4. Effective surface treatment to prevent corrosion.
5. High resistance to demagnetization; Excellent cost to performance ratio; Reasonable temperature stability; Not suitable for application which exposed in high temperature conditions.
Application of Sintered NdFeB:
Especially suitable for used in various electronic motors, engineering equipment, medical equipment, Health bandages and plasters, audio apparatus, Micro products of Auto, National defence, Security systems, Computer, Biology project, Instrument and Meter, household appliances, Magnetic separators, Magnetic resonance imaging, Specialty door catches, Filters & strainers, Sensors Speakers, Microphone/earphone, High performance motors, Brushless motor, Micromotor / servo motor, VCM(voice coil motor) Automobiles, Magnetic coupling Magnetic Chuck, Magnetic toy, Magnetic tools, Other magnetic applications.
