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.
- alloy Neodymium-Iron-boron digunakake kanggo nggawe wesi sembrani permanen.
- Kang digunakake ing Mikrofon, Mp3 pamuter, speaker, telpon seluler, etc.
