 | 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

- 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
