Tungsten is amazing for its strong physical attributes. It has the highest melting point of all the non-alloyed metals (3,410°C), the lowest vapor pressure and the highest tensile strength (19.3 gms/cc).

A steel-gray metal, tungsten does not occur naturally in its pure metallic state; rather, it is found in several ores, including wolframite and scheelite. Most of the world's reserves are in China, which supplies 85% of the world's demand. Tungsten is also found in Colorado, Russia, and Korea.

 

Tungsten History

Tungsten has a patchwork history, dating back to medieval German and Swedish smelters. The name tungsten is derived from the Swedish words "tung sten," meaning "heavy stone." Its chemical symbol, W, is derived from the German wolfram, the old name of the tungsten mineral wolframite.

One theory behind the name wolfram was that it was named from wolf rahm (wolf froth or cream), a reference to the large amount of tin that was devoured when the tungsten was smelted.

In 1781, a self-made chemist and scientist, Carl Wilhelm Scheele, and Torbern Bergman, a Swedish chemist and mineralogist, suggested it might be possible to obtain a new metal buy reducing tungstic acid. Two years later, in 1783, Jose and Fausto Elhuyar were the first to isolate tungsten through the reduction of this acid with charcoal. For this reason, they are credited with the discovery of this element.

 

Today’s Applications

In its raw state, tungsten is brittle and difficult to utilize. The pure form of tungsten is used mainly in electrical components. Tungsten is extracted from the crushed ore and then consolidated into a solid form.

Tungsten’s many composites and alloys are used in diverse applications and industries that range from aerospace and automotive to homeland security and sports and leisure. Its specific applications are almost endless and include weights and counterbalances, rotor blades, guidance platforms, vibration governors, radiation shielding, industrial instrumentation, gyro rotors and fly wheels, ordnance components, armor penetrating applications, boring bars, grinding quills, die cast tooling and many others.
