Sintered NdFeB Disc Magnet    

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

§ Microphone/earphone                      § High performance motors

§ Brushless motor                          § Micromotor / servo motor

§ VCM(voice coil motor)                    § Automobiles

§ Magnetic coupling                        § Magnetic Chuck

§ Magnetic toy                             § Magnetic tools

Sintered Neodymium-Iron-Boron magnets are kind of rare earth magnetic material developed recently in1980's, with magnetic properties far exceeding those of the Alnico and Ceramic/Ferrite types. They are alloys of elements, neodymium-iron-boron. The composition is Nd₂Fe₁₄B.

Our neodymium disc magnets are mainly used in holding equipment. Some small disc magnets with lower energy are also used in auto speakers.

We can provide low energy neo material with competitive price for holding equipment or auto speakers. But our high energy like N50 or N52 is really powerful for high performance holding equipment.
