Abstract：According to the working characteristics and performance of the steam turbine generator rotor winding wire, using copper silver alloy and adding trace rare earth elements to purify and improve alloy properties, different wall thickness rectangular hollow copper silver alloy wires was developed by means of casting, extrusion, drawing, annealing, drawing, annealing and drawing process. As product, tensile strength≮300 MPa, yield strength≮250 MPa, break elongation is 5 percent, Brinell hardness≮85. The minimum conductivity was 56 m/(Ω·mm2)at room temperature. When it was heated to 300℃and kept heating one hour, its Brinell hardness decreased by 10%and has good thermal stability.
