Adding elements such as manganese, nickel, and cobalt to copper-zinc brazing filler metal can improve wettability and significantly increase the strength of the brazed joint. When Mn is added, the tensile strength of joints brazed with YG8, YT5, YT15, and other cemented carbides can reach 300-320 MPa at room temperature. At 320°C, it still maintains 220-240 MPa. The addition of nickel can further enhance the wettability of the filler metal to cemented carbides, resulting in better brazing microstructure and performance, and improving the impact toughness and fatigue impact strength of cemented carbide tools.
1. Self-fluxing function: Phosphorus generates phosphate during brazing, reducing oxidation and eliminating the need for additional flux. 2. Low melting point and easy operation: Solidus temperature is approximately 645℃, liquidus temperature is approximately 815℃, suitable for heat-sensitive workpieces. 3. High conductivity: The conductivity of the brazed joint is close to that of pure copper, ensuring reliable electrical connection. 4. Excellent wettability: It wets copper, brass and other base materials thoroughly, resulting in a dense, pore-free weld.
