Silver base brazing alloys are commonly used for brazing most of ferrous and nonferrous metals alloys. These families of filler metals have a lower brazing temperature due to Sn addition thus offers excellent flow. Meanwhile, the high content of Ag in the alloys guarantees a good corrosion resistance. However, the detrimental effect was shown when it joints in stainless steel. In present work, corrosion behavior of silver-copper-tin brazing alloy was evaluated. The brazing alloy was exposed to water contained chloride and the temperatures were varied at 25, 40, 55, and 70 °C. The electrochemical methods were utilized to evaluate the corrosion behavior of the alloy. The results showed that the dissolution of Sn seems to be initiating the corrosion of the silver-copper-tin brazing alloy. Nevertheless, the active dissolution of the Cu to the solution simultaneously influence the corrosion behavior of the silver-copper-tin brazing alloy. This study in terms of the alloy corrosion behavior in the particular environment should give both of academicals and industrials contributions.
