3 Uses
3.1 Uses & Benefits
- Its has very limited uses and its alloys are very hard and are used in the manufacturing of pen tips, pivots, needles and electrical contacts.
-
It is also used as industrial catalyst to speed up the chemical reaction.
- Currently known uses of Darmstadtium metal are limited to research purpose only. As only few atoms of this metal are produced.
