Product features
- Temperature resistance from -250°C to +250°C.
- SmCo magnets are corrosion resistant and do not require additional coating in many applications.
- Suitable for applications in humid or chemically demanding environments.
- The coercivity (Hc) of SmCo magnets is very high and makes them resistant to demagnetisation.
- Low temperature coefficient of permeability, which ensures magnetic stability at temperature fluctuations.
- Other sizes available on request.

Technical Drawing
Areas of application
SmCo magnets (samarium cobalt magnets) are highly resistant to temperature fluctuations and corrosion and are extremely resistant to demagnetisation. These properties make them ideal for long-lasting, high-performance applications in demanding environments:
- Automotive industry: SmCo magnets are used in ABS systems to accurately monitor wheel speed, which is essential for the functioning of the anti-lock braking system. They are also used in the electric motors of hybrid and electric vehicles, where their high performance and efficiency are impressive. SmCo magnets are a long-lasting and reliable solution in actuators, such as those needed for precise control of seat adjustments or side mirrors.
- Electronics: In electrical engineering, SmCo raw magnets are in particular demand due to their high magnetic force and small size. They are used in micromotors, where they enable high performance despite their compact size, and are therefore used in devices such as cameras or small household appliances. SmCo magnets are also widely used in sensor technology, particularly in magnetic field sensors and magnetoresistive components, which are needed for precise measurement and control.
- Science and research: SmCo magnets are used in laboratory equipment and experimental setups to enable highly precise measurements and controls. Their consistent magnetic performance, even under extreme conditions, makes them ideal for applications such as spectrometers, magnetic resonance imaging scanners and other scientific instruments.
Another significant area of use is in particle accelerators, where SmCo magnets act as essential components of magnetic lenses. These magnetic lenses focus and control the path of charged particles to ensure accurate and controlled experiments. Due to their temperature resistance and demagnetisation strength, they remain stable even at high energy densities and complex stresses, which is crucial in basic research and the development of modern technologies. - Aerospace technology: The magnets are used in sensors to enable precise position measurements and control tasks. In engine components, their temperature resistance and high magnetic stability ensure reliable operation even at very high temperatures, as they occur in aircraft engines or in space travel.
