Ulah lan Wuku
- Wesi saka Rhenium digunakake minangka materi kontak listrik. Iku bisa nolak tahan karat busar.
- katalis digunakake ing hidrogenasi kimia nggoleki. Sawijining campuran karo nikel digunakake kanggo gawé glathi turbin.
- 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.
