Interesting things about tungsten
Technical Characteristics
Tungsten heads the group of the most refractory metals and is widely used in modern industry because of its exceptional properties. Under normal conditions this metal does not react with any chemical substances, its density is identical to that of gold. The melting point of tungsten: 3387-3422 ° C, this metal is used in the targets of X-ray machines, as well as for the manufacture of filaments in the lamps, heating devices, electron beam tubes.
