Samarium cobalt magnets are ideal for applications requiring high magnetic strength and temperature resistance, such as aerospace, motors, and medical devices.

SuperMagnetMan carries four samarium cobalt (SmCo) grades: SmCo18, SmCo26, SmCo30, and SmCo24H. These grades vary in magnetic strength and temperature resistance—SmCo18 and SmCo26 provide excellent stability for high-temperature environments, SmCo30 offers higher magnetic performance, and SmCo24H is engineered for applications requiring both strong magnetism and superior heat resistance.

Samarium cobalt (SmCo) magnets offer lower maximum strength than neodymium magnets, but they provide much better temperature stability and corrosion resistance. Neodymium magnets are the strongest rare earth magnets available, ideal when maximum magnetic power is required. SmCo magnets, on the other hand, are preferred for high-temperature or harsh environments where neodymium may lose strength or require protective coatings. 

Yes, SmCo magnets are stocked in multiple shapes and sizes, including discs, rectangles and ring magnets, so you can test under harsh conditions before moving to full production.

Yes. Through our engineering division, SM Magnetics, we can design and manufacture custom sizes, magnetization directions, and specialized coatings. You can either submit a custom request form or contact us directly to speak with our experts.
