Facts
Interesting Facts
  • 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.
  
  • Magnesium ions are present in every chlorophyll of every green plant .
  • Controlling Magnesium fire by pouring water on it will result in explosions.

Uses
Uses & Benefits
  • 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.
  
  • Magnesium aluminum alloy improves the mechanical strength and welding characteristics and hence it is used in aeroplane and car manufacturing.
  • It is also used to remove sulfur from the molten iron and steel.
