SmCo Magnets

SmCo Magnets

Sintered samarium cobalt (SmCo) magnets are powerful, often used in applications under high temperature due to their superior temperature stability. It is often used in applications that require high-temperature work, such as generators, pump couplings, sensors, motors, marine applications, as well as automotive, aerospace, military, food, and manufacturing industries benefiting from its high temperature and corrosion resistance characteristics.

Our smco disc magnets are a powerful blend of samarium, cobalt, neodymium, iron, and boron. These rare-earth magnets boast high magnetic energy, making them ideal for applications where strong magnetic fields are required. Their robust performance ensures reliability in even the most demanding environments.
