Uses
Uses & Benefits
  • Currently known uses of Darmstadtium metal are limited to research purpose only. As only few atoms of this metal are produced.
  
  • Dysprosium metal is highly reactive due to which it pure form is not as usual as its alloy.
  • Thi metals alloy is used in magnate as it is resistance to high temperature.
