Samarium cobalt (SmCo) block magnets are a type of rare earth magnet that are composed of samarium, cobalt, and other elements such as iron, copper, and zirconium. They are known for their strong magnetic field, high magnetic stability, and resistance to demagnetization.
We can provide our customers with customized samarium cobalt products and related solutions, which are highly resistant to corrosion without coating.
SmCo block magnets are often used in applications where a strong and stable magnetic field is required, such as in electric motors, generators, sensors, and magnetic bearings. They are also used in aerospace, defense, and medical applications.
Compared to other types of magnets, SmCo magnets have a high resistance to corrosion and can operate at higher temperatures, up to 350°C.
