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.
- Thallium minangka logam beracun lan panggunaane winates. Logam thallium biasane digunakake kanggo ngasilake sel fotolistrik.
- Ing paduan merkuri termometer nduweni 8% saka thallium, amarga titik leleh luwih murah tinimbang 20 ° C.
