Tungsten Components

Featured Product from Plansee SE

Guaranteed purity

Are you looking for truly excellent quality? Then you need us. We produce our tungsten products ourselves - from the metal powder right through to the finished product. As our input material, we use only the purest tungsten oxide. This ensures that you benefit from a very high level of material purity. Find out for yourself.

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.

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.

Pure Tungsten - or Maybe an Alloy?

We prepare our tungsten to perform perfectly in its specific applications. We can determine the following properties through the addition of various alloys:

-Physical properties (e.g. melting point, vapor pressure, density, electrical conductivity, thermal conductivity, thermal expansion, heat capacity, electron work function)
-Mechanical properties (e.g. strength, fracture behavior, creep resistance, ductility)
-Chemical properties (corrosion resistance, etchability)
-Machinability (e.g. cutting processes, formability, weldability)
-Microstructure and recrystallization behavior (recrystallization temperature, embrittlement, aging effects)
