The aging behavior of Cu-0.39Cr-0.11Zr-0.12Y alloy was investigated in this paper. The results showed that the tested alloy could obtain higher electrical conductivity and microhardness in solution at 960 °C for 1 hour under various deformations and aging at 480 °C condition than that of the alloy in solution-aged condition. The strength of the tested alloy increased with the increased deformation by cold working, the highest tensile strength value reached 637 MPa, while the elongation and electrical conductivity dropped a little. The values of tensile strength, electrical conductivity and elongation were 603 MPa, 79.66%IACS and 9.8% respectively when the second pulling deformation increased to 75.0%, that would meet the requirement of contract wire used in electrical high-speed railway.
