Samarium Cobalt

The original “rare earth” magnet material, Samarium Cobalt (SmCo) has been commercially available for more than three decades. While it has been replaced in many projects by newer materials, SmCo continues to perform in applications where no other materials can provide the required combination of characteristics.
SmCo magnets boast a unique set of attributes – high magnetic strength, excellent corrosion resistance, and good stability at elevated temperatures. SmCo magnets can be used in situations where operating temperatures will exceed 500° F. As a result, in applications requiring a strong, corrosion resistant magnet that will be exposed to high temperatures, SmCo remains unmatched.
