Applications
| Application | Role | Significance |
|---|---|---|
| SmCo permanent magnets | SmCo5 and Sm2Co17 alloys | Operate to 350 °C; preferred for missile guidance, traveling-wave tubes, satellite actuators where NdFeB cannot survive [4] |
| Defence electronics | SmCo magnets in radar, EW, and precision-guided munitions | US DLA classifies SmCo as a critical defence material with no qualified substitute |
| Aerospace actuators | High-temperature servo motors, gimbal drives | Stable flux density and corrosion resistance vs. NdFeB |
| Optical filters | Sm-doped glass and CaF2:Sm phosphors | UV-blocking optical components, IR luminescence |
| Catalysis | Sm(III) catalysts in organic synthesis | Niche pharmaceutical and fine-chemical use |

Verified Offers
All in-stock retail and bulk listings normalised to USD/kg. Sourced from primary surveys of eBay, Alibaba, and Western specialist retailers. The retail premium for hand-portioned metal samples is dramatic: the auto-rendered table below shows oxide bulk at single-digit dollars per kilogram while gram-scale metal trades above $9,000/kg.

Important Notes
Export controls in force
Samarium is one of the seven medium and heavy rare earths controlled under MOFCOM/GAC Announcement No. 18/2025. SmCo magnet alloys and finished magnet rotors are explicitly named in the controlled item list [2].
SmCo > NdFeB at high temperature
Samarium-cobalt magnets retain useful coercivity to 350 °C, well above NdFeB’s ~200 °C ceiling. This makes SmCo irreplaceable in missile guidance, satellite actuators, and high-temperature servo motors. There is no engineering substitute.
Co-production constraint
Samarium is recovered as a by-product of Nd/Pr separation from bastnaesite. Supply cannot scale independently of light rare earth output, meaning Sm prices respond more to magnet-grade Nd demand than to Sm-specific demand.
