- metal Gold utamané dipigunakaké kanggo Jewelry, bullion, koin, etc.
- Kang digunakake ing seni, hiasan, ornamen, etc. Sampeyan uga dipigunakaké kanggo proses listrik.
- 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.
