Aluminum and its alloys, due to their low density and high specific strength amongst various structural materials, are potential candidates for many automotive and aerospace applications. Al alloys on high thermal conductivity and mechanical properties are expected to replace the use of copper alloys in applications. Thermal conductivity influences the performance of alloys as a crucial function and is essential to extend the life of the materials due to uniform temperature distribution. In the present study, we studied effects of element addition on microstructure and mechanical properties of Al-Zn-Cu based alloys. Experimental specimens are manufactured by casting and hot extrusion. The electric and thermal conductivity of as-cast and as-extruded Al-Zn-Cu based alloys were investigated with addition of additive elements. Mechanical properties of the specimens were evaluated by tensile test at room temperature and the results were correlated with development of the microstructure.
