A previous study concerning the characterization of CuNiSi (C70250) and CuCrZr alloys showed very interesting characteristics of toughness evaluated with tensile tests and preliminary tests on Charpy specimens. These alloys could have interesting applications such as devices used for energy production, particle physics and aerospace. These alloys are used in the ITER (International Thermonuclear Experimental Reactor) project, an international program of great interest. For this reason, it seems important to characterize the mechanical properties of these alloys.

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.
