近几年来,随着铝及其合金在工业上应用日益广泛,通过钎焊方法制造铝及其合金的结构受到愈来愈多的注意。LD_5(AK_6)是很重要的航空铝合金,用它制造的某些结构必须通过钎焊方法来完成。然而,目前对于LD_5铝合金钎焊的研究还不多,为了适应生产发展的需要,我们对 LD_5铝合金的钎焊进 In recent years, with the increasing industrial application of aluminum and its alloys, more and more attention has been paid to the structure of aluminum and its alloys by brazing. LD_5 (AK_6) is a very important aviation aluminum alloy. Some structures made from it must be made by brazing. However, at present, there is not much research on the brazing of LD_5 aluminum alloy, in order to meet the needs of production development, we braze the LD_5 aluminum alloy
