7 Uses
7.1 Uses & Benefits
- Currently known uses of Darmstadtium metal are limited to research purpose only. As only few atoms of this metal are produced.
- This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
- Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
