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.

Iki digunakake kanggo harden baja lan mrodhuksi stainless steel lan macem-macem wesi liyane.
Iki uga digunakake kanggo menehi finish sing tepat kanggo mirrors polesan. Piring kromium digunakake ing perlengkapan jedhing.
