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.
