The invention discloses a preparation method of an Al-CuZn bimetallic conducting material. The preparation method of the Al-CuZn bimetallic conducting material comprises the steps that firstly, CuZn alloy is prepared through induction smelting; secondly, an aluminum block and the CuZn alloy are pretreated; and finally, the pretreated aluminum block and the pretreated CuZn alloy are placed into a hot-pressing grinding tool for vacuum hot-pressing sintering, and thus the Al-CuZn bimetallic conducting material is obtained. According to the preparation method of the Al-CuZn bimetallic conducting material, by adding Zn into copper, the lattice constant and other properties of copper are changed, the liquid-solid diffusivity of pure copper and aluminum on an interface is reduced, generation of intermetallic compounds including CuAl2 and Cu4Al9 is restrained, and the interface structure of the Al-CuZn bimetallic material is improved; by means of the different melting points of aluminum and copper, it is guaranteed that the pure aluminum with the molten surface and the solid CuZn alloy form a good transition interface through diffusion under the high-temperature condition, and metallurgical bonding of aluminum and the CuZn alloy is achieved.
