Samarium cobalt magnets: high-performance & temperature-resistant

Samarium Cobalt magnets (SmCo) are powerful rare-earth magnets made primarily from samarium and cobalt, often alloyed with iron, copper, and other elements for enhanced performance. These magnets are known for their exceptional thermal stability, high magnetic strength, and natural resistance to corrosion – making them ideal for demanding industrial and aerospace applications. While not as strong as neodymium magnets, SmCo magnets maintain their magnetic properties in environments where others fail, especially at elevated temperatures.

✓ Corrosion resistant
✓ Maintains magnetic strength

Working with custom Samarium Cobalt magnets also presents unique challenges. SmCo is a brittle material, which makes it more difficult to process and handle compared to other magnetic materials. It requires precise engineering and careful assembly techniques to prevent cracking or breakage during machining or integration. At Bakker Magnetics, we have extensive experience as a SmCo magnets manufacturer. Our engineering teams develop robust, reliable SmCo magnet solutions that meet the exacting demands of applications in aerospace, automotive, medical, and industrial sectors.
