Features & Characteristics of Samarium Cobalt Magnets

SmCo magnet is a kind of strong permanent magnet with excellent magnetic properties. It has excellent temperature stability and has high corrosion and demagnetization resistance. Due to the above features and characteristics of Samarium Cobalt magnets, they are very suitable for applications involving high or extremely low temperatures.

Available Grades for SmCo Magnets

SmCo magnets come in a variety of grades to meet a wide range of application requirements. Stanford Magnets currently stocks a large number of SmCo magnets in grades 18 and 26, but not all of them are on this website. So if you are looking for SmCo magnets, please don't hesitate to contact us or send us a special request to let us know your requirements.

Temperature Considerations for Samarium Cobalt Magnets

The maximum operating temperature of SmCo magnets is between 250 and 550°C and they have a Curie temperature range of 700 to 800°C.

Common Applications of SmCo Magnets

As I mentioned above, SmCo magnets feature excellent temperature stability while retaining their magnetic properties under extreme temperature conditions. Thus, they are very suitable for applications that require high performance and magnetic strength in high or low-temperature environments. Nowadays, SmCo magnets are widely used in the military, wind energy, semiconductor, petroleum, manufacturing, aerospace, medical, automotive, electric power, and energy industries. Today, Samarium Cobalt magnets can be found in high-performance motors, actuators, generators, turbomachinery, electric motors, magnetic separation devices, traveling wave tubes, magnetic couplings, magnetic bearings, sensor systems, drilling equipment, wind turbine equipment, energy recovery systems, medical devices, missile components, industrial automation equipment, pipeline inspection, robotic arms, gyroscopes, accelerometers, particle accelerators, sputtering deposition, magnetic drive components, Halbach arrays and more.

The Manufacturing Methods of Samarium Cobalt Magnets

The most commonly used method of manufacturing SmCo magnets is the sintering method. SmCo magnets can also be manufactured by injection molding and compression bonding methods.

The Bonding Methods of SmCo Magnets

People usually use "superglue" such as Loctite 325 to assemble SmCo magnets into products. It is best to avoid mechanical stress on this material and always make sure that the bonding surface is dry and clean before bonding.

Safety Precautions While You Are Using SmCo Magnets

Samarium Cobalt magnets are hard, quite brittle, and have high magnetic strength. During transportation and installation, please ensure that the magnet is not subject to severe impact. If the method is improper during transportation and installation, it is easy to cause damage and cracking of the magnet. As SmCo magnets are very strong, one should avoid hands or other parts of the body from being clamped by the magnets during operation. While handling larger SmCo magnets, please pay more attention to personal safety. Finally, please do not place SmCo magnets where children can reach them to prevent children from eating by mistake.
