Antiwear SGS Circular Ring Samarium Cobalt SmCo Permanent Magnet Rotor Motor
Samarium cobalt magnet, also known as samarium cobalt permanent magnet, is a powerful permanent magnet made of samarium and cobalt. And Ndfeb, also belong to rare earth magnets. Currently, it mainly consists of SmCo5 and Sm2Co17.
Although SmCo is less magnetic than NdFeB, SmCo offers two distinct advantages: a higher temperature range and better corrosion resistance. Therefore, they provide the best value when comparing performance and size in high-temperature environments or applications.
Characteristics & Application of SmCo Permanent Magnet
1. SmCo permanent magnet has high magnetic energy product and high cercive force. Its properties are better than AINiCo, ferrite permanent magnet. Its max energy product is up to 239kJ/m3(30MGOe), which is three times of that of AINiCo8 permanent magnet, eight times of that of ferrite permanent magnet. So the permanent magnetic component made from SmCo material is small, light and stable in property. It is widely applied to electro acoustic & telecommunication apparatus, electric motors, measure meters, peg-top, electronic watch, microwave apparatus, magnetic mechanism, sensor and other static or dynamic magnetic routes.
2.The curie temp. of the SmCo permanent magnet is high and its temp. Coeff is low. So it is suitable for use at 300 high temp.
3.SmCo permanent magnet is hear and bristle. Its rigidity strength, tensile strength and press strength are low. So it is not suitable for framework.
4.The main ingredient of SmCo permanent magnet is metal cobalt (CY99.95%). So its price is high.
