Samarium Cobalt Rare Earth Magnets

Samarium cobalt magnets (also known as SmCo magnets), are extremely powerful permanent magnets. Part of the rare-earth magnet family, SmCo magnets rank similarly in strength to neodymium magnets but have much higher temperature stability and higher coercivity. They can operate at temperatures up to 525°F (300°C). In addition, they have a very high resistance to demagnetization and to corrosion. SmCo magnets are available in numerous shapes, sizes and grades that span a wide range of properties and application requirements. Samarium Cobalt magnets exhibit good corrosion resistance when compared to Neodymium magnets. For most applications, a coating or plating is not required, but it should be considered when operating in environments that are acidic, have high moisture, or are in a vacuum.
