Sintered Samarium Cobalt rare earth magnets are extremely resistant to demagnetization and can operate at temperatures up to 500°F (260°C). There are many Samarium Cobalt grades which can withstand higher temperatures, but several factors will dictate the overall performance of the Samarium Cobalt rare earth magnet. One of the most pertinent variables is the geometry of the magnet or magnetic circuit. Samarium Cobalt magnets, which are relatively thin compared to their pole cross-section (Magnetic Length / Pole Area), will demagnetize easier than Samarium Cobalt magnets which are thick. Magnetic geometries utilizing backing plates, yokes, or return path structures will respond better to increased temperatures. The maximum recommended operating temperatures listed on the Samarium Cobalt magnetic characteristics page do not take into account all geometry conditions. Please contact a MPCO team member for Samarium Cobalt rare earth magnet design assistance when elevated temperatures are involved in your application.
High Corrosion Resistance Performance Motor SmCo Arc Magnets
High-Performance Magnets with Excellent Temperature Stability Custom Rare Earth Magnets, Rare Earth SmCo High-Performance Segment Strip Magnet Samarium cobalt magnets (also known as SmCo magnets), are extremely powerful permanent magnets. Part of the rare-earth magnet family, SmCo magnets rank similarly in strength to neodymium magnets but have much higher temperature stability and higher coercivity. They can operate at temperatures up to 525°F (300°C). In addition, they have a very high resistance to demagnetization and to corrosion. SmCo magnets are available in numerous shapes, sizes and grades that span a wide range of properties and application requirements. Rare Earth SmCo Countersunk Segment Magnet

YXG-30H High Performance SmCo Segment Tile Magnets
SmCo magnets are a type of rare earth permanent magnet which made of an alloy of Samarium, Cobalt, and Iron. Besides excellent resistance to oxidation and corrosion, SmCo arc magnet has a high Curie temperature and stable temperature stability compared with Neodymium magnets. Almost all of SmCo arc magnet is used in high temperature permanent magnet motors, generators, and coupling devices due to its abnormal temperature holding feature. High-Performance Excellent Temperature SmCo Magnet Arcs, Higher Working Temperature Samarium Cobalt Sector Segment Magnet
Samarium cobalt magnets are often used in applications involving elevated temperatures where magnetic strength and stability are critical, space is a limiting factor and where the magnets may be exposed to radiation. They are routinely used in high-performance motors, machinery, pumps, medical devices, magnetic couplings, magnetic separators and other equipment for automotive, aerospace, medical, military and industrial automation industries. We are trusted partners to businesses worldwide in these primary markets.
