Samarium cobalt permanent magnet (SmCo) is a permanent magnetic material primarily composed of the metals samarium and cobalt. There are two main types of samarium cobalt magnets: 1:5 and 2:17. This material is characterized by its stable magnetic properties, excellent heat resistance, and superior corrosion resistance. With a maximum working temperature of up to 350°C, it is highly suitable for the manufacturing of high-performance permanent magnet motors and products that require exceptional performance in demanding working environments.
