Abstract
The inter-metallic compound layers at the interface in copper/aluminum clad metal sheet were investigated. In this study, three ply clad sheets, comprised of copper (C1100), aluminum (A1050) and copper (C1100) were fabricated by means of hot-rolling process and heat treatment was carried out at 500 ºC. The phase analysis of compound layers was carried out and the change of hardness at the Cu and Al interface was investigated by nano-indentation. The thickness of the compound layers was measured at heat treatment time form 10 min to 90 min, and the electric resistance, tension and adhesion tests on the clad sheets were carried out. The correlation between the compound layers of clad metal sheet and the mechanical properties by time variation of heat temperature were studied.
