As a novel deposit process, many researchers have focused on Cold Spray. Up to now, few studies about mechanical properties of Cold Spray deposits have been reported and it has still not been well understood how they are determined in cold spray process. In the case of industrial applications for Cold Spray technology, since lack of data on deposit properties such as physical, mechanical and electrical properties, the prevalence of the technology has been obstructed. In this study, we investigated mechanical properties of Cold Spray deposits both as sprayed and heat-treated such as Cu, Al, Stainless Steel 316L and Ti. It was found that the higher operating gas temperature leads to the stronger rupture strength for each deposit. All the deposits as sprayed had no elongation. But after heat treatment of the deposits, some showed elongation and the others showed no elongation.
