Samarium Cobalt (SmCo) is a high-performance permanent magnet material made from the rare earth metal samarium and the transition metal cobalt. It is mainly divided into two series: 1:5 type and 2:17 type. Featuring high maximum energy product, strong coercivity, excellent high-temperature resistance, oxidation resistance, and outstanding magnetic stability, it can operate reliably in environments above 300°C. It is widely used in aerospace, precision instruments, microwave devices, and high-end motors.
