SmCo Magnet
SmCo magnets, the other rare earth magnet except NdFeB magnet, the same as NdFeB, SmCo magnets can also be subdivided into different grades, widely used in different areas. It can be divided to two categories SmCo5 and Sm2Co17.
Property
The Curie temperature of SmCo magnet can reach 710-880 °C, the maximum working temperature can reach 250-350 °C, which is higher than NdFeB’ highest working temperature 230 °C;

SmCo magnet has better corrosion resistance property than NdFeB magnet .When the working temperature is higher than 150 °C, samarium cobalt has lower flux loss than NdFeB magnet, 1:5 type samarium cobalt (SmCo5) has the maximum energy product 8 MGOe (140 kJ/m3), and the Br reversible temperature coefficient is -0.04~-0.05%/°C; 2:17 type samarium cobalt (Sm2Co17) has the maximum magnetic energy product 30 MGOe (240 kJ/m3), it is difficult to be processed, the carbon content is lower than that of 1:5 type, and the raw material cost is lower relatively; 2:17 type samarium cobalt has great corrosion resistance property and magnetic property stability in thermal state. Compared with other rare-earth permanent magnetic materials, its reversible temperature coefficient is -0.02~-0.035%/°C, which is the minimum of all magnetic materials.
Application fields
It is suitable for the applications which has high requirement on working in environment of high temperature, high humidity and high corrosion resistance, it was widely used in such as : Servo motor, water pump connector and sensor etc.
Performance chart of SmCo magnet
Note:
1. Due to The Fast development Of Technology, The Performance Index May Be Adjusted Accordingly time to time.
2. In addition to above grade, we can also provide custom-made grade and performance, Welcome to contact us.
