Samarium Cobalt round Sm2Co17 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.
picture showed the round sm2co17 magnet,the process way is metal samarium,cobalt, copper, iron, zirconium, according percentage to melting, grinding, profiling, sintering, aging, and make of various grades, shapes and sizes.

The (BH)max between 20-32, the maximum operating temperature can be reached 350 °C, the 2:17 has a low temperature coefficient (-0.02% / ℃) and good corrosion resistance, magnetic properties is more than NdFeB magnets when in high working temperatures,
The Curie temperature is high to 840-870 degrees, higher than Smco5.
The disadvantage is that the process is complex with high costs.
