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.

Beneficial Suggests:
Sintered SmCo permanent magnetic materials have the character of great brittleness and lacking of the ductibility, therefore, it isn't suitable for the material to be applied as structural parts when designed. The physical characteristics of SmCo5 is better than Sm2Co17's. Because SmCo5 is slightly easier to be machined while Sm2Co17 is more brittle. Magnetized SmCo products must be picked up carefully and gently during assemble process and kept away from ironware to avoid mutually attracting, causing chips and cracks or other damage to magnets' appearance, or it will even hurt operators in case that two strongly magnetized slices firmly attract unexpectedly.
