Keyword:  Al-Si-Cu-Zn钎料铝及铝合金钎焊力学性能;
Abstract: 采用4种Al-Si-Cu-Zn钎料钎焊纯铝和6063铝合金,研究不同成分钎科的钎焊工艺性能和接头力学性能.试验结果表明:Al55Si10Cu20Zn5钎料熔点最低,固相线为499.5 ℃,液相线为523 ℃,比传统的Al-Si钎料液相线降低了60 ℃左右;Al65Si10Cu20Zn5钎料相对于其他3种Al-Si-Cu-Zn钎料,与QJ201钎剂或QF钎剂匹配,在纯铝和6063铝合金上均具有最佳的润湿性;采用QJ201钎剂,A165S110Cu20Zn5钎料无论在钎焊纯铝还是6063铝合金时,均具有最高的抗剪强度.
