SmCo magnet
SmCo magnet up to 350°C
The magnets obtained by sintering have an extremely high temperature resistance up to 350°C, with additional protection even 400°C. They are distinguished by their high strength and high remanence. They also have a high degree of coercivity and corrosion resistance. Due to high cost of raw material, they are ranged at the high end of the cost and quality curves. They are mainly used in the automotive industry, in electric motors, sensors, etc.
