According to the copper-silver alloy contact wire, the tensile strength of the copper-silver alloy contact wire is improved from common 380 MPa to 440 MPa or above, the electric conductivity can still be kept at 90-98% IACS, the current-carrying capacity is not obviously reduced, and the requirements for train speed increasing and special environments are met. The copper-silver alloy wire is a single copper-silver alloy wire with the cross section area larger than or equal to 120 mm < 2 > and comprises, by weight, 0.06%-5.0% of silver, less than or equal to 0.1% of mixed components and the balance copper and inevitable impurities, the mixed components are composed of 0.02%-0.06% of Ga, 0.01%-0.04% of La and 0.01%-0.02% of Ti, and the total mass of the inevitable impurities is not larger than 0.02%.
