Due to extreme hardness and density, tungsten is often used to obtain hard metal alloys. Its high melting point makes it a good material for making rocket nozzles, turbine blades and wear resistant parts etc. The alloys of tungsten are used in automotive industry and the aerospace industry as well.
Tungsten is used in making many electronic types of equipment such as light bulbs, cathode ray tubes, vacuum tube filaments, heating elements, electronic contacts etc. Some other equipment which can be made using tungsten is field emission guns, electron microscopes and transistors, etc.
C. Gold substitution
Since the density of tungsten is very high and is quite similar to that of gold, it can be used as a gold substitute and is used for making Jewelry, etc. It is used for making resist which are resistant to scratching and counterfeiting of gold bars, etc.
