Tungsten and molybdenum wide applications are as followings:

Electric light source and electric vacuum
Since Edison invented the incandescent lamp, tungsten applied in the lighting field has been more than 100 years of history. From the initial thermal radiation source to the more efficient gas discharge light source, the core status of tungsten in electric light source has never shaken. Electro luminescence light source subverts the understanding of people on the electric light source material, but tungsten as core material of electric light source will exist for a long time. Tungsten materials are also widely used in various electronic vacuum devices, including the magnetron, high voltage rectifier and others.

Semiconductor and electronic technology
Semiconductor and electronic technology are the foundation of nowadays technology. Transistor and complex circuit are formed on Si substrate by magnetron sputtering technology, which is the most basic productive process of chip and all kinds of electronic devices. Magnetron sputtering targets made of tungsten and tungsten alloy has become indispensable materials in electronic technical field, due to the stable chemical and physical properties, high melting point, high electrical conductivity, high electromigration resistance and excellent step coverage performance.

In semiconductor technology, particular the integrated circuit (LSI),  photovoltaic (PV) and other fields, tungsten and tungsten alloy are widely applied.
As for the rapid developing LED lighting technology, the production of the sapphire substrate needs high temperature resistant and long service life materials as the crucible, heater, heat shield. At present, only tungsten and molybdenum materials can meet the requirements.
