Magnetic property of Smco magnets, Products attribute of smco magnets,  application of Smco magnets

SmCo magnet is a rare earth metal samarium and cobalt-based strategy elements, with iron, copper, zirconium, praseodymium and other metal materials ratio of melting into the alloy, grinding, pressing, sintering and aging made of a magnetic materials with higher magnetic properties (high energy product, high coercivity, high remanence); very low temperature coefficient (-0.030% / ℃), high temperature (maximum temperature is 350 ℃), negative temperature limitation, the working temperature above 180 ℃, the maximum energy product, temperature stability and chemical stability are more than NdFeB material; has a strong anti-corrosion and oxidation resistance. Therefore, SmCo magnet is widely used in aerospace, defense industry, microwave devices, communications, medical equipment, instruments, wind power, a variety of magnetic drives, sensors, magnetic processor, high-end motor, etc.
magnetic pump Application:
  There is a non-magnetic pump seals leaking transmission fluid fog machine. Mainly for the centrifugal pump vane pump design, in a sealed external cavity with a rotating magnetic field, and through the magnetic field to drive inside the sealed chamber synchronous rotating magnetic rotor components, and sealing the internal cavity of the rotor components driven fluid acting on the impeller to achieve. Since the axis of rotation of stator components do not wear clothing with shield seal body. To ensure zero leakage of magnetic pump, no pollution. SmCo magnet with its stable energy product, high temperature (350 ℃) for excellent performance, widely used in magnetic pump.
Sensor Applications:
  Magnetic sensor system requires permanent magnetic materials can be integrated to provide a stable magnetic properties, NdFeB maximum use temperature of 150 to 200 ° C, the reversible temperature coefficient of -0.1 to -0.13% / ° C, can not meet the high-end magnetic sensor system requirements, and the highest temperature is 350 ℃, the reversible temperature coefficient of -0.030% / ° C and NdFeB material with unmatched corrosion resistance materials as high-end sensor system Sm2Co17 the most appropriate permanent magnet materials.

client purchase strong magnets"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

customers buy permanent magnets"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
