The influence of the addition of Mn and Sn elements on the microstructure, melting characteristics, and wettability of low-silver Ag20Cu35Zn(43.5-x-y)MnxSnyNi1.5 brazing alloys was investigated, and the content of Mn and Sn elements in the brazing alloys was optimized. Subsequently, the Ag20Cu35Zn31Mn10Sn2.5Ni1.5 foil-filler brazing alloy was prepared using a single roller cold method. Its performance in connecting YG15 cemented carbide and 42CrMo dissimilar steel material was then investigated through high-frequency induction brazing at 790 ~ 870 ℃. The results showed that an increase in Sn element content lead to the coarse brittle phases with a high volume fraction in the brazing alloy, and the types of the brittle phase were diversified. An increase in Mn element content caused the brazing alloys to undergo brittle phase refinement, elevation of the solidus, and a reduction in the melting range, displaying a trend of increasing and then decreasing surface areas of YG15 and 42CrMo. Optimal comprehensive properties of the brazing alloy are observed when the mass fraction of Sn and Mn elements was 2.5% and 10%, respectively. The joint shear strength between YG15 and 42CrMo brazed with Ag20Cu35Zn31Mn10Sn2.5Ni1.5 foil-filler brazing alloy at a temperature of 830 ℃ reached a maximum value of 270.36 MPa. The shear strength was comparable to that brazed with commercial Ag30CuZn brazing alloy at 850 ℃. The shear fracture was in the weld, and the fracture was a mixture of ductile fracture and partial brittle fracture.
