Abstract:Ag is used as a beneficial alloy element in no matter solders or brazing filler metals. Obviously, the addition of Ag has a positive function on melting temperature, wettability, mechanical property and conductivity of filler metals. Therefore, Ag is still widely used in many researches and production in spite that Ag is very expensive. Respectively, three kinds of typical solders (Sn-Zn, Sn-Bi, Zn-Al) and brazing filler metals (Ag-Cu-Zn, Cu-P, Zn-Al) were selected as the representative. The research status on the Ag-contained filler metals and the influence rules of Ag addition on the change of filler metals physical property and microstructure as well as mechanical property were reviewed. Moreover, the problems and difficulties in the process of studying Ag-contained solders and brazing filler metals were presented. Synchronously, some suggestions were put forward to solve the problems and difficulties mentioned above, which provides theory guide for the follow-up study of Ag-contained solders and brazing filler metals, and their prospects were also prospected.
Key words: Ag; Ag-contained alloy; wettability; solder joint; solder; brazing filler metal
