The grain size of W-Cu nano-composites would greatly affect the density of W-Cu alloy. In this work, W-Cu oxide nano-composite powders were prepared by sodium tungstate and copper nitrate via hydrothermal method, and W-Cu nano-composite powders were obtained by subsequently co-reduction process. The characterization of W-Cu nano-composite powders were carried out by X-ray diffraction(XRD), scanning electron microscope(SEM), energy spectrum analysis(EDS) and transmission electron microscope(TEM). The results indicated that hydrothermal method was a good method for the preparation of W-Cu oxide nano-composite powders. W-Cu nano-composite powders, whose grain size was about 70nm and distributed uniformity, were manufactured by co-reduction process.
