Ulah lan Wuku
- Magnet saka campuran kobalt Samarium luwih kuwat tinimbang wesi lan mula digunakake ing aplikasi gelombang mikro.
- Logam Samarium uga digunakake ing laser optik lan kaca tingal nyerep infra merah lan minangka penyerap neutron.
- Sampeyan uga dipigunakaké ing insecticides, alami rambute lan minangka aditif anti-nuthuk kanggo bensin. Nanging kabeh iki dilarang déning pamaréntah minangka logam Lead dikenal kanggo ngrugekake kanggo kesehatan.
