Introduction The demand for advanced materials with multiple functions and enhanced properties increased as the technology advanced.
The properties of clad composite material are determined by the selection of component materials to be joined, the stacking structure of different materials with various thicknesses and interface structure and properties between different materials.
Several method such as extrusion, rolling, electro-plating, overlay welding and explosive welding have been used for the clad materials production.
Materials used in this study were copper and aluminum of the commercial purity.
