Ulah lan Wuku
- Silver utamané dipigunakaké kanggo Jewelry lan nuduhake Piece.
- Kang digunakake kanggo Manufaktur mirrors kualitas dhuwur amarga bisa reflectivity sawijining.
- Dysprosium logam reaktif amarga kang wangun murni ora minangka biasanipun minangka alloy sawijining.
- Thi alloy logam digunakake ing magnate iku resistance kanggo suhu dhuwur.
