Uses
Uses & Benefits
  • Currently known uses of Darmstadtium metal are limited to research purpose only. As only few atoms of this metal are produced.
  
  • Its alloys are used to make engine parts, drills, saw blade, etc.
  • Lubricant additive made up of Molybdenum disulfide is commonly used in the industry. It is also used as a catalyst.
