Powerful Samarium Cobalt Sm2Co17 Smco ring Magnet Smco Magnet supplier
Samarium Cobalt (SmCo) magnets are composed of Samarium, Cobalt and other metallic rare earth materials. SmCo Ring Magnet is a common shape of SmCo Rare earth magnets. SmCo Magnets are perfect for high temperature application, as they can work properly at 250-300 °C. Bearheart Magnets provide SmCo Ring Magnets for various applications. Samarium Cobalt magnet holds its standard property in higher maximum temperatures than neodymium magnet, although its maximum strengh is less. The cost of SmCo material is the most expensive, so SmCo is recommended only when its performance is a high temperature environment is a concern.

Features
1. SmCo permanent magnet has high magnetic energy product and high coercive force. Its properties are better than Alnico, ferrite permanent magnet. Its max. energy product is up to 239kJ/m3(30MGOe), which is three times of that of AlNiCo8 permanent magnet, eight times of that of ferrite permanent magnet (Y40). 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. smco square magnet
2. The curie temp. of the SmCo 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(CoY99.95%). So its price is high.
