Abstract—The influence of Sn addition on the microstructure, melt properties and mechanical properties of Ag-Cu-Zn-Sn braze filler were investigated in this study. Microstructural analysis reveal that increase of Sn content with increased the eutectic phase and promote the formation of Cu3Sn intermetallic compound. The differential thermal analysis show that increase of Sn content dramatically decrease the melting temperature of the Ag-40Cu-1Zn-7Sn braze filler are
<700 oC. The tensile strength and elongation of brazing joint was improved by increasing Sn content in braze filler.
Index Terms—Ag-Cu-Zn-Sn braze filler, brazing, melt properties, microstructure, mechanical properties.
