Advantages of Tungsten semi-finished products

Tungsten excels through its outstanding thermic and electric conductivity, high density, resistance against thermic shocks, corrosion resistance and high melting point. In its pure condition the shiny white metal is known as brittle heavy metal with a high density and in comparison to other metals it has the highest melting point and the second highest boiling point.

History and Discovery

Tungsten is a chemical element for which the symbol “W” is used. The name is derived from the Swedish Tung Steen, meaning heavy rock. In 1781, Carl Wilhelm Scheele discovered a previously unknown salt, calciumtungstate, which was not the substance known today as tungsten but wolframite. Only afterwards, the brothers Fausto and José Elhuyar under the lead of Carl Wilhelm Scheele discovered tungsten by reducing tungsten trioxide.

Products from Tungsten

In its pure condition, tungsten could not be traced anywhere on this planet yet. The best-known reservoirs worldwide are China, Peru, the US, Russia and Austria. It is assumed that the total amount of tungsten worldwide adds up to app. 2,9 million tons. The US are among the biggest miners of tungsten while China is the largest producer with a market share of 80%. This is certainly due to the fact that a multitude of electronics is produced there.

Applications of Tungsten semi-finished Products

Its material properties make tungsten a broadly applicable material for demanding and critical applications uses which allow no material failure such as aeronautics, semiconductors and electronics, industrial furnaces and many additional applications. One of the best knows examples is the filament in lightbulbs.

Tungsten Alloys

Aside from highly pure tungsten, HWN titan GmbH also offers tungsten alloys, so called doped tungsten. This way, material properties can be improved by adding potassium for higher temperatures in a targeted way. For example, potassium doped tungsten is used in lighting industries. In the product form rod doped tungsten has a higher strength, and by adding Lanthanide high heat resistance and electrical behaviour are improved. Tungsten in connection with Lanthanide provides a better tracking resistance and recrystallisation temperature.
