Exhibits characteristics in severe environments such as rust and high temperatures.
It is composed of cobalt and the rare earth element samarium. Samarium-cobalt magnets have high magnetic properties, second only to neodymium magnets. Compared to neodymium magnets, they have the advantages of being less prone to rust and being resistant to high temperatures. On the other hand, they are hard and brittle, so they need to be handled with care. Taking advantage of their high heat resistance, they are mainly used in sensor components, medical device components, and so on.

Applications/Examples of results
Samarium cobalt magnets have a higher maximum operating temperature compared to neodymium magnets. Therefore, they are suitable for use in high-temperature environments. Their applications range widely, from household appliances like microwaves and ovens to industrial products such as automotive magnets and various actuators. Taking advantage of their resistance to demagnetization even at high temperatures, they are used in vacuum tubes called magnetrons inside microwaves and in automotive applications such as motors and ignition systems.
