Samarium Cobalt Magnets
1. High magnetic strength: up to about 32MGOe.
2. Can operate at temperatures up to about 300°C.
3. No need for surface coating treatment.
1. Very brittle and difficult to process.
2. Since this material contains cobalt, the cost is relatively high.
Since most grades of samarium cobalt magnets contain little or no iron, which gives them excellent corrosion resistance, neodymium magnets typically contain 60-75% iron. Therefore, SmCo magnets generally do not require electroplating.
Compared with NdFeB magnets, the magnetic properties are not as good as SmCo magnets, but they are stronger than ordinary ferrites, equivalent to low-grade NdFeB magnets.
SmCo magnets are widely used in aerospace, defense and military industries, microwave devices, communication equipment, medical equipment, instruments, sensors, motors, magnetic cranes, etc.
"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!!"

"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."
