and convert this 4' into <Ag-゛> as shown in Figure 2.
600 to 9 even if a brazing material 5 such as wax or Au wax is used.
When brazing is performed in the atmosphere at 00°C, the diffusion of Ti in the core material 1 is suppressed by Mo in the intermediate layer 7, thereby preventing the formation of intermetallic compounds. Therefore, there is no peeling after brazing, and good brazing with high brazing strength can be obtained.
