The novel Al-Si-Zn filler metals containing Ti and Sr were used for brazing of 6061 aluminum alloy. The results indicate that the addition of Zn into the Al–Si filler metal lowers the solidus temperature from 583 °C to around 520 °C. The minor addition of modification element Sr and refine element Ti into Al-Si-Zn alloy WILL cause the remarkable modification of Al-Si eutectic and the α-Al phase is also refined. The main phases in the filler metals as well as the brazed seams are α-Al, η-Zn, and Si phases. The large clusters of Al-Si eutectic in the Al-Si-Zn-Sr-0.04Ti brazed seam are refined by further adding 0.08 wt% Ti, the refined Al-Si eutectic is homogeneously distributed among α-Al phase. Diffusion layers can be found in the brazed interface, the Mn-Fe phase is also found in the brazed seam due to the diffusion of 6061 base metal into the brazing alloy which is helpful for reduce the formation of acicular β-Fe
