You can find tungsten at work whenever the heat's on. Because no other metal can compare with tungsten when it comes to heat resistance. Tungsten has the highest melting point of all metals and is therefore also suitable for very high-temperature applications. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability. Tungsten is practically indestructible. For example, we use this material to manufacture high-temperature furnace components, lamp components and components for use in the fields of medical and thin-film technology.

A material with special talents.

The very special industrial applications in which our tungsten is used reflect the unique properties of the material. We briefly present three of these below:

Outstanding creep resistance and high purity.

Our tungsten is very popular for use in melting and solidification vessels in the field of sapphire crystal growth. Its high level of purity prevents any contamination of the sapphire crystal and its good creep resistance guarantees the product's dimensional stability. Even at extremely high temperatures, the results of the process remain stable.

High purity and good electrical conductivity.

With the lowest coefficient of thermal expansion of all metals and a high level of electrical conductivity, our tungsten is the perfect material for thin-film applications. Its high level of electrical conductivity and low diffusivity to neighboring layers mean that tungsten is an important component in thin-film transistors of the sort that are used in TFT-LCD screens. And, of course, we are also able to supply you with the coating material in the form of ultra-high purity sputtering targets. No other manufacturer is able to supply tungsten targets in larger dimensions.

Long service life and an extremely high melting point.

With their long service lives even at extremely high temperatures, our tungsten melting crucibles and mandrel shafts are able to withstand even quartz glass melts without difficulty. Thanks to the outstanding purity of our tungsten, we can reliably prevent any bubble formation or discoloration of the quartz melts.
