Samarium cobalt magnet, also known as samarium cobalt permanent magnet, is a powerful permanent magnet made of samarium and cobalt. And Ndfeb, also belong to rare earth magnets. Currently, it mainly consists of SmCo5 and Sm2Co17.
Although SmCo is less magnetic than NdFeB, SmCo offers two distinct advantages: a higher temperature range and better corrosion resistance. Therefore, they provide the best value when comparing performance and size in high-temperature environments or applications.
