Interesting Facts
- Beryllium is best anti corrosion metal.
- Beryllium is the lightest metal and still it is stronger than steel.
- It also finds various applications in Nuclear reactors as a reflector.
- Naturally occurring minor elements include Cadmium.
- Cadmium is released into atmosphere to control volcanic eruption and forest fires.
- It is used for electroplating of Steel for corrosion resistance.
- It can absorb neutrons and used in nuclear reactor to control atomic fission.

Uses & Benefits
- Its alloys with copper or nickel are used in manufacturing Gyroscopes, springs, electrical contact and non sparking tools.
- Beryllium Alloys are used as a material for aircraft, missiles, spacecraft and satellite.
- It has very limited uses as it is a toxic metal and it can cause birth defects, cancer, etc.
-
Almost 80% of Cadmium metal is used in Nickel cadmium Batteries and now it is getting replaced with nickel hydride.
