Progress in Manufacturing and Alloying of AgCuZnSn Brazing Filler Metals

Sn is used as a beneficial alloy element in silver based brazing filler metals. Obviously, the addition of Sn has a positive function on melting temperature, wettability, filling performance and mechanical property of the sliver based brazing filler me-tals. AgCuZnSn brazing alloys is used as a green and environment-friendly filler metals, which has been a hot topics in the brazing aca-demia at home and abroad. The research and development of the AgCuZnSn brazing alloys during the past two decades are reviewed synthetically. First, the properties of AgCuZnSn brazing alloys are outlined. Secondly, the preparation methods of AgCuZnSn brazing alloys are discussed. Thirdly, the research progress of alloying on the AgCuZnSn brazing filler metals, and the effect of In, Ga, Ni, P, La, Mn element and Ni-P, Ga-In, Ga-In-Ce alloy on AgCuZnSn brazing alloys are reviewed. Lastly, the current problems of the AgCuZnSn brazing alloys are presented, some suggestions are also given for solving these problems, and the future development direction of the AgCuZnSn brazing alloys is prospected, which can provide the theoretical guide and reference for the research of AgCuZnSn brazing alloys.
