ｉを中間層とし 。(Prior art and its problems) Conventionally, Ti-containing noble metal solders have been produced using molten metal because when they are made into alloys, plastic working becomes difficult due to the formation of intermetallic compounds between Ti and various metals. An alloy powder is obtained by atomizing, or a noble metal alloy is used as an intermediate layer and the surface is clad with Ti, or vice versa.
Let i be the intermediate layer.

う問題があった。On the other hand, although composite brazing filler metals clad with Ti and precious metal alloys are effective in plastic workability, it takes time for Ti and precious metal alloys to melt together and form an alloy during brazing. There were problems in that it would take a long time and cause segregation.

ものが得られる。(Structure of the Invention) The Ti-containing composite brazing filler metal of the present invention has Ti uniformly dispersed in a noble metal alloy, and the manufacturing method thereof is as follows:
Powder or grains of powder or grains of noble metal solder are mixed in a proportion according to their composition ratio, and after repeating compression molding and sintering, a wire or plate-shaped material is obtained using an extruder. be. By using this method, since Ti is uniformly dispersed in the noble metal alloy in the state of a single metal, no intermetallic compound of Ti is generated. Even if it were formed, it would only be a surface layer of Ti, so the material after extrusion could be easily finished into a predetermined size by drawing or rolling without losing plastic workability. When Ti, Ti alloys, or ceramics are brazed using this Ti-containing composite brazing material, since Ti is uniformly dispersed in the precious metal alloy, molten alloying is completed in a short time, and the structure after brazing is Also, segregation is extremely low and bonding strength is improved compared to conventional ones.
