Application & Usage of Pure Tungsten
Application & Usage of Pure Tungsten
Tungsten is a steel-gray to tin-white metal. Tungsten has the highest melting point and lowest vapour pressure of all metals, and at temperatures over 1650C has the highest tensile strength. The pure tungsten is used mainly in electrical applications, but its many compounds and alloys are used in many applications, most notably in light bulb filaments, X-ray tubes (as both the filament and target) , and superalloys.

WC
Tungsten carbide (WC) is an inorganic chemical compound containing equal parts of tungsten and carbon atoms. It's extensively used in industrial machinery, tools, abrasives, as well as men's jewellry. Tungsten carbide is four times stiffer than steel and is a much denser metal than steel or titanium.
