    Abstract: A method for manufacturing a welding material includes: a compound preparing step in which a compound is prepared by mixing alloy powder containing first alloy powder having a first average particle size and second alloy powder having a second average particle size, a water soluble binder and water; a drying step; an extruding step; a degreasing step in which the extruded formed body is heated to a predetermined temperature of 400° C. or above; a C—O reaction step in which the extruded formed body is heated to a predetermined temperature which falls within a range of 950° C. to 1150° C. under a vacuum atmosphere; and a sintering step in which the extruded formed body is heated to a predetermined temperature which falls within a range of 1200° C. to 1350° C. under a nitrogen gas atmosphere thus forming a welding material.

    Abstract: Atomized Cu—Cr alloy powder, 20 to 30 percent by weight of Thermite Cr powder and 5 percent by weight of electrolytic Cu powder are mixed together and undergo solid phase sintering treatment to form an electrode material for vacuum circuit breakers. The gross content of Cr of the electrode material is 30 to 50 percent by weight. In manufacturing the electrode material for vacuum circuit breakers, such powders are mixed together and then undergo compression molding to be formed into a compressed compact. The compressed compact is performed solid phase sintering at a temperature lower than the melting point of Cu in a non-oxidizing atmosphere to prepare a solid phase sintered body.
