In this paper, a new type of electrical contact materials was prepared by adding a small amount of V and Zr to Ag-Cu alloy, and the properties of alloys containing different amount of Zr were determined. The properties of Ag-10Cu-0.3V-1Zr alloy are as follows: Resistivity: 2.27μΩ · cm Temperature coefficient of resistance 3.02 × 10 -3 / ° C Thermoelectric potential 0.47μV / ° C for steel Elastic modulus E 8000kg / 2 Tensile strength 72kg / mm ~ 2 (hard) Vickers hardness 158kg / mm ~ 2 (hard)
