This is a small square smco magnet with a middle through hole, made of Sm2Co17 grade 26 material by Chinese magnet manufacturers, the surface is not coated, is a natural color, mainly used in light isolators, high temperature environment products.
SmCo samarium cobalt magnet is a superior permanent magnetic material, which not only has high magnetic properties, but also has strong corrosion resistance, oxidation resistance, low temperature coefficient, high Curie temperature, and can be used in higher ambient temperatures. Under use. SmCo permanent magnets are widely used in motors, meters, sensors, detectors, radar detection, microwave devices, national defense industry and other high-tech fields.
Samarium cobalt magnets can be processed in shapes: wafer, ring, square, tile, U-shaped, and special shapes.
