Samarium-cobalt magnets, due to their high magnetic energy product, extremely low temperature coefficient, and excellent corrosion and oxidation resistance, are widely used in aerospace, defense, medical equipment, and high-precision sensors. They are employed in devices that need to operate long-term in high-temperature and highly corrosive environments, such as rocket thrusters, turbine engines, and high-performance magnetic couplers. Additionally, samarium-cobalt is suitable for high-demand applications such as military missile guidance systems and satellite communications.
