description	The invention relates to a preparation method of a Cu-Y3Zr4O12 composite material with excellent comprehensive performance. The preparation method comprises the following steps: (1) carrying out solid-liquid coprecipitation; (2) calcining; (3) mechanical alloying; and (4) spark plasma sintering. Composite oxide powder is obtained through solid-liquid coprecipitation and calcination methods, and composite oxide particles are added into a copper matrix through a mechanical alloying method, so that the dispersion strengthening effect is achieved. Different from a traditional oxide, the composite oxide is uniformly dispersed and distributed in a copper matrix, interfaces between the nano-scale oxide particles and the copper matrix are in a semi-coherent relationship, and the good interface relationship means stronger interface bonding force. The mechanical property of the material is greatly improved, and the conductivity is maintained at a relatively high level; the grain size of the copper-based alloy is refine
