Interesting Facts
- Fermium metal is highly radioactive in nature.
- Fermium is synthetically produced metal.
- Hafnium metal is highly reactive, hence not found free in nature.
- Hafnium metal as predicated after Mendeleev finished his periodic table.

Uses & Benefits
- Currently known uses of Fermium metal are limited to research purpose only.
- It has an ability to absorb neutrons and hence it is used to make control rods in nuclear submarines. And this metal is also used in Plasma welding torches.
-
It alloys with iron, titanium and niobium are very useful.
