Fracture toughness and tensile tests have been carried out on a CuCrZr alloy to characterize its fracture behavior since it is considered a possible candidate for the construction of a passive satellite. Based on the satellite design requirements some copper-based alloys have been studied. These alloys are interesting candidates for the satellite construction because of their physical properties, such as high thermal conductivity and density, and because of their mechanical properties, in fact CuCrZr alloy is age hardenable.

The diffusion of copper weapons during the late 4th and 3rd millennia BC in the Southern Levant marks a distinct transformation of the economy and society of this region, as it coincides with the earliest urban experience. This paper provides an overview of copper and copper-alloyed weapons through a study of the technology and functional features of this material at the key site of Tell es-Sultan/Jericho in Palestine.
