| In nature tungsten is found in more or less the same quantities as copper (average content of tungsten in the earth's crust is aprox. 70 g/t). It has a base-centered cubic lattice and with 3420 °C the highest melting point of all metals. |
The discovery of tungsten is attributed to the brothers J.J. and F. Elhuyar, two Spanish chemists, who worked in Sweden. Its common English name, tungsten (in many other languages it is known as wolfram), is derived from a Swedish word meaning "dense stone".
Since the beginning of the 20th century, PLANSEE is one of the most important producers of tungsten. Thanks to many years of experience in the production and processing PLANSEE today offers a wide range of mill and final products made of tungsten and W-alloys.
