Why is the tungsten used almost exclusively for filament of electric lamps?

 

Answer

Tungsten metal is used exclusively for making the filament of electric bulbs because it has a very high melting point.

Due to its high melting point, the tungsten filament can be kept white hot without melting away.

Other reasons for using tungsten are

  • It is highly flexible
  • It has a low rate of evaporation at high temperature.
