Technical characteristics

Tungsten disc is made from high metal and high purity with the highest possible density. The total amount of tungsten in the final product is not less than 99.99%. This, as well as the smallest possible grain size in the microstructure of the products leads to their widespread use in semiconductor, chemical vapor deposition, physical vapor deposition, and various optical parts and components. Products are produced using crystallization, solid state and other ultra-pure purification processes such as sublimation.
