Ulah lan Wuku
- aplikasi utama Rubidium iku ing Manufaktur kaca.
- Rubidium bisa banget gampang njaluk ionized lan Empu iku digunakake kanggo mesin ion, nanging isih kurang efisien tinimbang sing saka Caesium.
- Kang utamané dipigunakaké kanggo galvanizing logam.
- Iku uga digunakake kanggo Manufaktur die-casting lan iku banget penting kanggo industri automobile.
