In this study, copper powder + Ca thermal reduction molybdenum trioxide powder was obtained using water atomization process. Mo80Cu20 composites material with excellent performance and high density was prepared by copper infiltration method. By controlling the sintering temperature of molybdenum-copper composites material, a denser and more excellent performance composites material was obtained. Experimental results show that the density of molybdenum-copper composites material prepared by infiltration method reaches as high as 99.4 %, and the physical properties of the molybdenum-copper composites material prepared by infiltration method at sintering temperatures ranging from 1300℃ to 1400℃ are superior to those prepared by liquid phase sintering method. At a temperature of 1350℃, the thermal conductivity of the copper infiltration sintered product increased from 141.2 Wm−1K−1 to 179.7 Wm−1K−1, the electrical conductivity increased from 19.6 MS/m to 25.8 MS/m, Vickers hardness increased from 173 HV to 214 HV, and tensile strength increased from 401 MPa to 713 MPa.
