- Silver utamané dipigunakaké kanggo Jewelry lan nuduhake Piece.
- Kang digunakake kanggo Manufaktur mirrors kualitas dhuwur amarga bisa reflectivity sawijining.
- Wis cenderung kanggo njaluk tarnished ing online mbukak, nanging nalika alloyed karo unsur kaya erbium, vanadium, tingkat atose sudo.
- senyawa kaya Erbium oxide digunakake ing kaca tingal safety saka welders lan buruh metal.
