Samarium Cobalt (Rare Earth) Magnets are often used in high temperature applications needing high magnetic performance and where magnetic stability over a wide range of temperatures is important. Magnosphere can help optimize performance and cost with SmCo magnets in grades from 16 to 32 MGOe and temperatures up to 350°C/662°F. Samarium–Cobalt Magnet is a strong permanent rare earth magnet made of an alloy of samarium, cobalt, Fe, Cu, Pr and Zr.
Samarium Cobalt (SmCo) magnets are strong permanent magnets made of an alloy of samarium and cobalt. They are known for their high magnetic strength, exceptional temperature resistance, and reliable performance without oxidation protection. As a result, they are more suitable for certain applications than Neodymium magnets.
Temperature Considerations
A Samarium Cobalt magnet can withstand higher temperatures than a Neodymium magnet. The maximum operating temperatures for Samarium Cobalt magnets are between 250 and 550 °C; Curie temperatures range from 700 to 800 °C. Additionally, a Samarium Cobalt magnet is less subject to corrosion than a Neodymium magnet, and usually does not require coating or plating. sintered smco permanent magnets
Machining & Magnetization
Samarium Cobalt magnets offer strong resistance to demagnetization. All Samarium Cobalt magnets cannot be formed with conventional drilling, turning or milling processes, and must be ground before they are magnetized. Additionally, large or complex assemblies are usually magnetized prior to assembly. Standard tolerances for Samarium Cobalt magnets are +/-.005 for ground dimensions.
