Disk smco magnets
Samarium cobalt magnets (SmCo) are composed of samarium, cobalt and iron. These rare earth magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs.
 
Samarium cobalt (SmCo) are divided into different components based on SmCo5 and Sm2Co17. SmCo5 series of has a maximum operating temperature of 250C, while Sm2Co17 of 350C. Special grades of Sm2Co17 are available to even higher temperatures. Sm2Co17 offers 24 MGOe to 32 MGOe and is composed of about 25% samarium, 5% copper, 18% iron, 2% hafnium or zirconium, with the remainder being cobalt. Since Sm2Co17 requires extremely high magnetizing fields,multiple poles magnetization is not possible.
 
Samarium cobalt(Smco) magnet has a strong resistance to corrosion and oxidation resistance, usually do not need to be coated can be widely used in high temperature and poor working conditions.
