Homogeneous and nanostructured tungsten–copper–silver composite powders were synthesized via a chemical precipitation method to investigate the influence of silver on the properties of tungsten–copper composites. Ammonium metatungstate, copper nitrate, and silver nitrate were separately dissolved, and the initial precipitates were formed through reactions at controlled pH and temperature. These precursors underwent washing, drying, and calcination to yield oxide powders, which were subsequently reduced in a hydrogen atmosphere to form the final nanocomposite powders. Their characteristics were analyzed using X-ray diffraction, thermogravimetry, and scanning electron microscopy. The impact of sintering temperature on densification and hardness was systematically studied. Results indicated that the addition of silver improved the sinterability of the powders compared to standard tungsten–copper composites. Maximum relative densities of 97.7%, 98.2%, and 99.6% were attained for the composite powders sintered at 1200 °C, while maximum hardness values of 359, 349, and 255 Vickers were recorded for respective composite compositions. Overall, the incorporation of silver was beneficial in enhancing the consolidation and mechanical properties of the tungsten–copper composites.
