Samarium-cobalt magnets are divided to the SmCo5, or SmCo Series 1:5 and the Sm2Co17, or SmCo Series 2:17.   Sm2Co17 properties and SmCo5 properties are as described in our samarium cobalt properties & grades datasheet:

Samarium-cobalt magnets are brittle, and prone to cracking and chipping. Here are some typical mechanical properties of SmCo magnets:

Density: 8.2–8.4 (g/cm3)Samarium-cobalt magnets
Tensile strength: 35(N/mm2)
Flexural strength: 150 (N/mm2)
vickers hardness: 500-650 (HV)
