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.
Advantage:
• High precise geometry
• Homogeneous distribution of magnetic field
• Simple design and assembly, cost efficiency
• Precision of motor performances
• Huge marketing potential
Application:
• Actuators
• Magnetic bearings
• Magnetic clutch
• Motors (Peripheral motor, Spindle motor, Steering control
motor, Stepper motor)
• Other new products
Standard and skewed pole types are available for ring. OD, ID and H are all critical factors, pole numbers are also dependent on size, so for further information of radially orientated Sintered NdFeB rings, please contact us directly. Our engineer will evaluate your magnet design and give you some suggestion if needed.

Rare Earth Magnet for Magnetic Drive Pump
Magnetic Drive Pump solved work under corrosive, inflammable, explosive, toxic, leakage, and clean liquid environment. Permanent magnet in the magnetic drive pump refers to coupling magnet. Magnetic drive pump makes full use of performance of magnetic force on ferrous material and non-ferrous material.
The first generation magnet on pump magnet is ferrite magnet. It’s cheap and wide source. Due to poor magnetic performance, it limits the development of magnetic drive pump. The second generation magnet is samarium cobalt magnet and AlNiCo magnet. These two materials are better than ferrite, and let magnetic drive pump achieve large torque. But their cost is very high because material samarium and cobalt which used in smco and alnico are rare and strategic resource. It also restricts pump development. The third generation Sintered NdFeB magnet with (BH)max 207 kJ/m³ to 422 kJ/m³ is an ideal material for magnetic drive pump. Sintered NdfeB magnet is the strongest magnet which can reduce the volume of pump and its material Fe and Nd is rich than samarium, so price is affordable. It helps magnetic drive pump get the market finally.
China Magnets Source Material Limited is able to manufacture different kinds of high performance magnets for magnetic drive pumps. You are welcome to contact us for more information. Our engineers also are ready to provide technical assistance.
