Samarium Metal 99% is primarily utilized in the production of Samarium-Cobalt (Sm2Co17) permanent magnets with one of the highest resistances to demagnetization known. Samarium-149 has high cross-section for neutron capture (41,000 barns) and is therefore used in the control rods of nuclear reactors.
