Tungsten bar
It can be used as high-temperature heat source and high-temperature structure accessory.
Main applications:
Manufacture electric light source and electric vacuum accessory.
It can be used for make electrical contact.For stirring purposes in rare earth metals smelting and for making tungsten contacts and parts in electrical light sources making.
Tungsten's unique properties, including a melting point of 3410ípc, low vapor pressure at elevated temperatures and low coefficient of thermal expansion, make it of value in a variety of high temperature products and processes
Among them are glass-to-metal seal parts and support parts for lighting and electronics, silicon rectifier stud mounts and high temperature furnace components.
Sifon produces pure and potassium doped (wk type) tungsten rod
The potassium doped products is targeted for use where high temperature non-sag properties are required in smaller cross sections by the lighting and electronic industries.

Ultra high purity tungsten (5N or 6N) is often used as a gate, link and barrier metal in the electronic industry due to its high resistance to electron migration, high temperature stability and the formation of stable silicides. The ultra-high pure tungsten and tungsten or tungsten titanium silicon composite material is often made of sputtering target materials with high purity, in the form of the film covered on the substrate or other thin film layer, for very large-scale integrated circuit as a resistance layer, a diffusion barrier layer and the metal oxide semiconductor transistor as the gate material and link materials.
