            Production Process

            The production methods of tungsten and copper composites can be divided into four kinds: mixing and pressing sintering method, infiltration method, activation sintering method, nano\ ultrafine mixed powder sintering method.

            At present, the main method of preparing tungsten and copper materials is infiltration method. The advantages of this method are that the composition of the materials is more uniform, the density is high, the impurities are less, and the comprehensive properties are good. The theory of this method is to make tungsten skeleton with certain density and strength, and then infiltrated low melting point copper, a dense composite was formed by filling copper into the tungsten skeleton by capillary action.
