Abstract

PURPOSE:To construct an electrical material with the promotion made for increase of machining precision further with a metal sintered unit of high melting point being the main component, by applying the sintered unit, such as copper-tungsten, especially to improve a chamfering when starting the machining. CONSTITUTION:In the bottom center portion of a graphite vessel 15 is placed a tungsten skeleton 11, with a shank material 13 piled up on the above through a jointing material 12, and in a clearance with the vessel 15 is filled a copper powder as an infiltrating resolvent material 14, subsequently in a continuous hydrogen furnace is placed this vessel 15 with the infiltrating resolvent material made fusing and infiltrating uniformly into the skeleton, simultaneously with the joint layer constructed. Then with the clear applied in the periphery of electrode material except an area to be the electrode face of a sintered unit 21, after forming an insulation film, the electrode face is processed a buffing, degreasing and cleaning, and placed in a copper sulfate plating bath, and a copper playing is operated to the electrode face in a manner with the electrode material being the cathode and the copper plate being the anode.
