【摘要】 研制了铝基钎料ＬＡ_２、ＬＡ_３，锌基钎料ＬＺ_１、ＬＺ_２（ＬＺ_１是用于对比分析的标准钎料ＨＬ５０１）４种铝－铜钎焊材料通过对这些钎料及其钎焊接头的性能测试和组织成分分析认为ＬＺ_２是一种较为理想的铝－铜火焰钎焊材料。更多还原

【Abstract】 Two kinds of aluminium alloy brazing solders, LA2, LA3, and two kinds of zinc alloy solders, LZ1, LZ2, for Al-Cu joint welding are developed. Among the four solders the experiments show: the LZ1 solder is a standard solder for comparative analysis; the LZ2 is an ideal solder suitable for Al-Cu joint welding. The results were obtained through testing the performance and anaylzing the structure and the components of both the solder itself and the brazing joint.更多还原
