Beschreibung
Zusammenfassung:	The invention relates to high-strength lead-free brazing filler metal for brazing. The brazing filler metal comprises Zn, Si, Ge, Mg, Ti, Cu, C, In, Ga, Al, Mn, Fe, Y, Cr, Ni, Zr, V, Mo, Re, Pt, Bi, Au, W, a rare earth element and Sn. According to the high-strength lead-free brazing filler metal, the homogeneity and the wettability of an alloy are guaranteed, so that the brazing intensity is improved; and a tin-based brazing filler metal formula is changed, and B elements in a traditional formula is replaced with doped IVB group elements, so that the tin-based brazing filler metal intensity and toughness are improved, the brazing intensity is further improved on the premise that the brazing temperature is not improved, and the mechanical property of a brazing connector is guaranteed.
