Known as the Third Generation of Rare Earth magnets, Neodymium-Iron-Boron (NdFeB) magnets are the most powerful and advanced commercialized permanent magnets today. Since made from Neodymium, one of the most plentiful rare-earth elements, and inexpensive iron, NdFeB magnets offer the best value in cost and performance.
NdFeB magnets are available in both sintered and bonded forms. Sintered NdFeB offers the highest magnetic properties (33 MGOe to 51 MGOe) while Bonded NdFeB offers lower energy properties. Although bonded magnets do not possess magnetic properties as advanced as those of sintered magnets, they can be made in shapes and sizes that are difficult to achieve with sintering.
Why choose sintered NdFeB Magnets?
1. Chemical composition: Nd2Fe14B.
Neodymium magnets are hard, brittle and easily corrode.
2. Moderate temperature stability
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.
3. Excellent strength value
The highest (BH)max reaches up to 51MGOe .
4. Advanced Technology
The choice of Strip casting and HDDR technology in our factory allows us to make high performance NdFeB over N52 possible.
5. Extremely resistance to demagnetization with Hci
The intrinsic coercive force is over 30,000 Oe.
6. Effective surface treatment to prevent corrosion.
Surface treatments have been developed that allow them to be used in most applications. The treatments include gold, nickel, zinc and tin plating and epoxy resin coating.
7. Common uses in different fields:
· Security systems
· Magnetic separators
· Magnetic resonance imaging
· Health bandages and plasters
· Specialty door catches
· Filters & strainers
· Sensors
· Speakers
· Microphones/earphones
· High performance motors
· Brushless motors
· Micromotor / servo motors
· VCM(voice coil motor)
· Automobiles
· Magnetic couplings
· Magnetic Chucks
· Magnetic toys
· Magnetic tools
· Other magnetic applications
