摘　　要：配制4种成分的Al-Si-Cu-Zn钎料,并进行了差热分析、钎焊接头钎料组织及钎料铸态组织观察。结果证明,该钎焊料比传统的Al-Si钎料钎焊温度降低了60℃,并且焊接质量良好。Al-Si-Cu-Zn brazing fillers with four compositions were prepared in the test. it is proved that the fillers have better weldingquality, and lower welding temperature of 60℃ comparing to conditional Al-Si brazing fillers by aid of differential thermal analysis,observations for microstructure and as-cast structure of brazing fillers.
