Preparation Method of Novel Tungsten-copper-zinc Alloy Material

The present invention discloses a method for preparing tungsten alloys of copper and zinc.

Specific process is: will micron pure tungsten powder and tungsten coated copper powder and micron copper, zinc powder by mixing, extrusion and cold isostatic liquid spark plasma sintering (SPS) and other methods to prepare a The relative density of 95% or more of tungsten copper-zinc alloy material. The advantages: by the production method according to the present invention can be prepared in more than 95% relative density, but also has high hardness and high strength composite tungsten, Cu and Zn. Brass with respect to pure copper has high strength and hardness, integrated tungsten high strength, high density and high conductivity brass, high thermal conductivity, high strength and hardness properties, prepare a suitable spark processing, electronic packaging and aerospace materials in the field of high temperature, corrosion of tungsten alloy of copper and zinc.
