Samarium Cobalt Disc Magnets

Because Neodymium magnets do not perform well in high temperatures, the Samarium Cobalt disc magnets are often now used in high-performance motors. Accelerometers and gyroscopes - in aircraft, marine and spacecraft – as well as downhole drilling and many precision control systems take advantage of the temperature stability of Samarium Cobalt magnets.

While hard and brittle due to the sintering process that occurs during manufacturing, Samarium Cobalt magnets have the highest resistance to demagnetisation and outstanding temperature stability.

FAQ

What are Samarium Cobalt disc magnets typically used for? 
Samarium Cobalt disc magnets are commonly used in high-performance applications where temperature stability, corrosion resistance, and strong magnetic force are essential. These include aerospace components, medical devices, motors, sensors, and scientific instruments—especially in environments where heat or harsh conditions would degrade other types of magnets.

What are the advantages of using Samarium Cobalt over other magnet types? 
Samarium Cobalt magnets offer several benefits. They have a High magnetic strength, second only to Neodymium products and exceptional temperature stability (up to 350°C or higher). Samarium cobalt disc magnets have a natural resistance to corrosion, so no coating is needed, and they are reliable over a long period of time in harsh or demanding environments. These properties make SmCo discs ideal for precision engineering and mission-critical applications. 

Are Samarium Cobalt disc magnets brittle or fragile? 
Yes, like many rare earth magnets, Samarium Cobalt magnets are brittle and can chip or break if mishandled. While they are extremely strong magnetically, they are not impact-resistant and should be handled with care, especially in applications where mechanical shock is possible. Despite this, their durability under high temperatures and corrosive conditions makes them a trusted choice for demanding applications.
