These samarium cobalt magnet alloys have one atom of rare earth Samarium and five atoms of Cobalt. By weight this samarium cobalt magnet alloy will typically contain 36% Samarium with the balance Cobalt. The energy products of these samarium cobalt alloys range from 16 MGOe to 25 MGOe. These Samarium Cobalt magnets generally have a reversible temperature coefficient of -0.05%/°C. Saturation magnetization can be achieved with a moderate magnetizing field. This series of Samarium Cobalt magnet is easier to calibrate to a specific magnetic field than the SmCo 2-17 series magnets.
Machining or grinding this magnet by the user is discouraged. This material must be ground using diamond cutting and grinding tools and a significant amount of water based coolant. Dry ground powder can iqnite spontaneously with a small spark. Supply Russia Customer Samarium Cobalt Magnets

Sintered Samarium Cobalt magnets, similar to other magnet materials, are formulated for their magnetic properties and not their mechanical properties. As such, they must not be used as mechanical members, or expect to exhibit superior mechanical characteristics. As with sintered metullurgy, one should expect to find imperfections such as minor hairline cracks, porosity, voids, cold flow, shrinkage, pipe and others such as commonly found in cast or sintered metallic magnets.
