Abstract

PURPOSE:To improve the characteristic and manufacturing efficiency, by heating the cylindrical formed body mainly composed of tungsten with the infiltration material composed of copper or silver and impregnating the material into said body and at the same time, forming the substrate part composed of said material in the hollow part of the formed body. CONSTITUTION:Tungsten powder is put in a fixed mold and is pressed and then, the cylindrical formed body 1 is obtained. Next, said body 1 is baked in the hydrogen furnace and the copper 3 is put in the graphite vessel 2 using as the infiltration material and then, said tungsten baked body 1 is placed on the copper 3 so as to contact with it. Then, said vessel 2 is put in the continuous hydrogen furnance and is heated. The copper 3 is dissolved and is diffused into the body 1 and then, the cylindrical body made of copper-tungsten, is formed and also, the substrate part is formed by filling the hollow space 10 of the cylindrical body with the copper 3. Further, silver can be used in stead of said copper.
