N55 high grade sintered ndfeb magnet

With more and more the applications for rare earth permanent magnet material in the high-tech fields, the demand for special purpose and high performance rare earth permanent magnet material is also growing. But for a long time, high-end technology of the production of rare earth permanent magnet material has been mastered in the hands of the developed countries. With low performance magnetic materials, China has been in the laboratory research stage which is unable to be mass production.
To meet the challenge and development of the international market, through constant research and experiment, China Magnets Source Material Ltd., has mastered the formula of grade N55 sintered NdFeB magnet and achieved mass production, broke the monopoly of developed countries. High performance rare earth permanent magnet materials have been used in the aerospace, medical equipment, industrial motors etc.

Grade N55 Sintered NdFeB magnet is the strongest magnet in the market nowadays for commercial use. The magnetic energy product for N55 is 52-56MGOe; what needs to pay attention is that the maximum operating temperature for N55 is 60 degrees Celsius, but not 80 degrees Celsius as other N series grade.

Material grade N55 can also be made into a variety of shapes, including N55 round sintered ndfeb magnet, N55 square permanent magnet, N55 ring rare erath magnet, N55 cylinder strong magnet and so on. If you have demand, please feel free to contact us.

Radially Orientated Sintered NdFeB Ring

Due to the constraint of material, sintered neodymium used in motors is assembled into ring by segment magnet. China Magnets Source Material Limited can offer radially orientated Sintered NdFeB rings with a wide variety of grades and different coating options after researching continually in Sintered NdFeB material and its structure, orientation compression, magnetizing method, sintering and heat treatment process. Orientated Sintered NdFeB ring greatly improve motor output properties, significantly reduce the motor loss, at the same time.

How to choose a magnetic material? By china-magnets-source-material.com

When choose a magnet material, you need to figure out the requirement you need magnet to do in your application, but not blindly pursue high performance magnetic material; and then get a comprehensive understanding of different magnetic materials. If you have confusion on some point, you can ask for technical help from magnet specialist or manufacturer.

Material	Magnetic Property	Working Temperature	Corrosion Resistance	Price	Remark
NdFeB Magnet	high	low	low	high	1
Ferrite / Ceramic	middle	middle	high	low	3
SmCo Magnet	high	high	high	high	2
AlNiCo Magnet	low	high	high	middle	4

Ferrite and ndfeb magnet can be processed by sintering or bonding method. The Sintered magnet has high magnetic force, but poor formation. The bonded magnet has good formation, but low property.
Alnico can be processed by casting and sintering, the cast alnico has high property, but poor formation. The bonded alnico has good formation, but low property.

The magnetic field orientation for permanent magnet by china-magnets-source-material.com

Orientation direction: The direction where anisotropic magnets can obtain the best magnetic property.

Permanent magnets are divided into two types: Isotropic and Anisotropic.

Isotropic magnet: The magnet has same magnetic property in any direction.

Anisotropic magnet: The magnet has different magnetic property in different direction. And there is one orientation which can obtain the best magnetic property.

Sintered NdFeB magnet is anisotropic magnet. So the orientation (magnetized direction) should be decided before production.

Bonded NdFeB magnet is Isotropic magnet. If you buy uncharged magnet, there is no necessary to confirm magnetization direction.
