摘　　要：选用8213钎料、8515钎料和AlSiCsLa钎料进行火焰钎焊铜铝,结果表明:用这三种钎料焊接铜铝,接头都可以达到较高的强度,能满足一定的载荷要求.含有适量稀土元素的AlSiCsLa钎料,由于可细化晶粒、弥散分布脆性相、改善晶间组织,其焊接接头强度较高.Flame brazing copper and aluminum with 8213,8515,AlSiCsLa filler metal was investigated in this paper.The results showed that all welding joints with a high strength and endurance of a certain load were obtained.The joint welded by AlSiCsLa alloy could get a higher strength due to the brazing alloy containing a amount of rare earth elements which can refine grains,diffuse distribution of brittle phases and improve interface structure of crystals.
