3 Uses
3.1 Uses & Benefits
- Its alloys with aluminum and nickel are used to make powerful magnets.
-
Few other alloys exhibit high-temperature strength and hence they are used in Turbines of Jet and Gas engine.
- Currently known uses of Darmstadtium metal are limited to research purpose only. As only few atoms of this metal are produced.
