SmCo Cylinder Magnets

SmCo Cylinder Magnet

SmCo Cylinder Magnets are high-temperature resistant (up to 350°C), corrosion-proof permanent magnets. They outperform neodymium magnets in extreme environments while maintaining stable magnetic performance without protective coating. Commonly used in precision medical devices, aerospace systems and high-end industrial equipment, these durable magnets are available in standard and custom dimensions (SmCo26/SmCo28 grades). Their cylindrical shape makes them particularly suitable for rotary sensors and precision positioning applications.
