Samarium Cobalt (SmCo) Magnets

Samarium Cobalt (SmCo) magnets are high-performance rare-earth permanent magnets known for their excellent thermal stability, natural corrosion resistance, and strong resistance to demagnetization — maintaining reliable magnetic performance even in harsh environments such as high heat and humidity. Available in two main series, SmCo5 and Sm2Co17, they are widely used in aerospace, medical devices, automotive sensors, oil drilling, and military applications where reliability and durability are critical. SmCo magnets are a trusted permanent magnet solution for extreme operating conditions.
