We report molecular dynamics calculations on the evolution of Co-Au and Ag-Au alloy nanowires stretched along the ,  and  crystallographic directions. The strong tendency of chain formation has been found for Ag-Au alloy. On the contrary the Co-Au alloy presents a different breaking pattern. In particular, we have found the formation of tetramer alloy nanowires. Finally, we present the mechanical properties of alloy nanocontacts.
