Tungsten copper composite is composed of tungsten and copper, which are not mutually soluble and intermetallic compounds do not form intermetallic monomers. They are generally called tungsten copper pseudo alloys. In large-scale integrated circuits and high-power microwave devices, tungsten copper alloy sheet has broad application prospects as an electronic packaging substrate, connectors, heat sink and microelectronic shell materials.

In the field of electronics, such as the preparation of electric vacuum device with high emission rate of tungsten based cathode materials, in order to meet the requirements of higher quality performance reserve type cathode material, tungsten powder, which is more narrow in grain size and more slippery on the surface of the particle, should be used as a raw material than the present polygonal tungsten powder. 

Tungsten titanium alloy, due to its stable thermomechanical properties, is not only suitable for use in high current and high temperature environments, but also has a series of advantages such as low electron mobility, high corrosion resistance and good chemical stability, the best candidate for blocking the diffusion between Cu and Si / SiO₂.

Tungsten carbide / cobalt carbide alloys are widely used as cutting tools and die materials because of their high hardness and high wear resistance. The strength and wear resistance of tungsten carbide / cobalt cemented carbide can be significantly improved by decreasing the grain size of WC to ultrafine grain size (1um ~ 100nm) or even nano level (< 100nm). However, in the traditional liquid phase non pressure sintering process, the phenomenon of abnormal growth of ultrafine crystal WC particles is a headache.

Tungsten is an important rare metal element and has a wide range of uses in industry. There are two kinds of tungsten materials in industry, one is to extract tungsten from tungsten ore, which is called primary tungsten. The other is the recycle of waste products from tungsten, such as catalysts, waste alloys, the secondary resource called tungsten, tungsten resources become increasingly scarce, the proportion of secondary resources of tungsten is also growing.
