12x12 mm Samarium Cobalt MagnetSmCo

Samarium-cobalt (SmCo) magnet, a kind of rare earth magnet, is a strong permanent magnet consisting of two basic elements. The elements samarium and cobalt were used in a very powerful structure to create this permanent magnet.

SmCo samarium cobalt magnets are very similar in strength to neodium magnets. But it can withstand higher temperature.

Properties of Samarium Cobalt Magnets

• Samarium-cobalt magnets are extremely resistant to demagnetization.
• It is resistant to high temperatures. Maximum operating temperatures are between 250 Dec°C (523 K) and 550 Dec°C (823 K)]; Curie temperatures are between 700 dec°C (973 K) and 800 Dec°C (1,070 K).
• They are expensive due to the elements they contain.
• Samarium-cobalt magnets have strong resistance to corrosion and oxidation.
• They generally do not require coating
• They can be used extensively under high-temperature and harsh operating conditions.
• They are brittle and prone to cracking and crumbling.
• Samarium-cobalt magnets have maximum energy products (BH max) ranging from 14 megagauss-oersted (MG·Oe) to 33 MG·Oe; i.e. approx. Dec. 112 kJ/m³ to 264 kJ/m³; theoretical limits are 34 MG·Oe, approximately 272 kJ/m³.
