The application discloses a copper alloy material with super-high strength and high conductivity and a preparation method thereof. The copper alloy material is composed of the following components in percentage by mass: Ni: 5-13 wt.%, Sn: 6-14 wt.%, Sn:(Ni+Sn)=40-70 wt.%, M: 0.01-0.5 wt.%, and the rest is Cu, wherein the M is at least one selected from In, Al, Cr, V, Mn and Fe. The preparation process comprises the following steps: performing multi-stage homogenization treatment on a columnar crystal ingot with the above components, obtaining a super-fine crystal structure by performing cycle 'processing-current treatment' on the homogenization-treated ingot, and performing processing-aging treatment. The copper alloy material provided by the application has super-high hardness, tensile strength and good conductivity.
