摘　　要：将铟含量不同的Ａｌ－Ｓｉ－Ｍｇ－Ｉｎ焊料与Ａｌ－Ｍｎ芯材制成复合带材，研究了钢对复合带性能的影响．结果表明：钢含量对焊料与芯材的热复合性能影响不大；当铟含量一低于０．０２７％时，焊料中铟含量越高复合带强度和钎焊性能越好；当ｗＩｎ高于０．０２７％时，随焊料中钢含量的增加，复合带强度和钎焊性能反而下降；焊料中铟的最佳含量ｗＩｎ为０．０２７％．Composite strips were prepared by the use of Al-Si-In solder with different indium contents and a Al-Mn core material. The effect of indium on the performance of composite strip was studied. The results show that indium content has a slight influence on the thermal compounding performance of the solder and the core material; the composite strip's strength and brazability increase (when WIn. is lower than 0. 027%) and decrease (when wIn is higher than 0. 027%) with the increase of indium content in the solder. The optimal indium content in the solder is 0. 027%.
