Baoji Hanz Material Technology Co., Ltd. are directly manufacturer of tungsten, molybdenum, tantalum and other refractory metals with 8 years' experience.


Today let us know What is tungsten ?

 

Tungsten, (or Wolfram as it is known in many parts of the world) is an extremely hard and very dense gray to white metallic element extracted from wolframite, scheelite and other minerals. Tungsten has the highest melting point, lowest coefficient of expansion and lowest vapor pressure of any metal. It is also corrosion resistant and does not break down or decompose. Due to its unique attributes tungsten has few, if any, replacements in a majority of its industrial applications.


HARDNESS

Second only to diamond (tungsten carbide)

Industrial applications - high speed cutting tools, heavy machinery, specialty alloys


HEAT RESISTANCE

Highest melting point and lowest coefficient of expansion of all metals

Industrial applications - jet turbine engines, light bulb filaments


DENSITY

Greater than lead and uranium

Industrial applications - sporting goods (golf clubs, tennis racquets, darts), ballast


ENVIRONMENTALLY BENIGN

Does not break down or decompose

Industrial applications - sports fishing weights, shotgun shot, new applications being developed as an alternative to lead
