Samarium cobalt magnets 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.
According the composition, we divide two of SMCO: Sm2CO17 and SmCo5
According the process, we divide to sintered Smco and bonded Smco

Bonded SmCo
