With its unique mechanical and chemical properties, molybdenum is an outstanding material that can meet the most exacting requirements. Because molybdenum possesses a very high melting point, a low coefficient of thermal expansion and a high level of thermal conductivity, it is used in many different industries. Molybdenum is a genuine all-rounder. We use this material, for example, to produce ribbons and wires for the lighting industry, semiconductor base plates for power electronics, glass melting electrodes, hot zones for high-temperature furnaces and sputtering targets for coating solar cells and flat screens.

Applications
The industrial applications for our molybdenum are as varied as its properties. We briefly present three of these below:
High purity and excellent creep resistance
Our molybdenum is exceptionally pure, withstands very high temperatures and is nevertheless still easy to machine. For example,to produce crucibles for all the conventionally employed processes in the field of sapphire growth. Thanks to their exceptional purity, these have proved their worth as optimized melting and solidification vessels.
