samarium cobalt magnets are composed of samarium, cobalt and iron.
Compare Sm2Co17, the price is higher, it is not easy brittle
The (BH) max range is from 16 to 25, maximum working-
temperature 250°C. The physical character and ductibility is
better than Sm2Co17, so 1:5 samarium cobalt magnets are easier to be machined
thin thickness disc or ring wall and complex shapes which
Sm2Co17 are difficult to make.
