Applications:
High purity tungsten bars are used in the field of national defense, military weapons and precision electronic industry and other precision technology and materials, to prepare rods or tungsten wires, or as high performance electrodes, heating elements or high temperature components.
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.
