Facts
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.
  
  • Zinc metal found (obtain) in many forms like granules, foil, dust and in a powder form.
  • After iron, Zinc metal the second most abundant element in the earth crust.

Uses
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 corrosion resistance and hence it is used to plate other metals.
  • Its alloys are very useful; Nichrome alloy is used in the hot coil of toasters and electric oven.
