The invention relates to a tungsten-copper composite material forming part and a preparation method thereof, and belongs to the technical field of metal composite materials. The raw materials of the forming part are composed of a tungsten source, a copper source and a forming agent. The tungsten source consists of modified tungsten powder and tungsten powder; the modified tungsten powder is obtained by adding a reinforcing phase and an activating element, wetting and adhesion of a tungsten phase and a copper phase can be promoted, the sintering performance of the formed part is improved, and the comprehensive performance of the formed part is improved; the forming agent is added to ensure that the powder has good flowability and formability, the problems that a large-size tungsten-copper blank is poor in compression molding formability and high in manufacturing cost are solved, and a tungsten-copper composite material formed part which is uniform in structural component, low in cost and easy to form is obtained. The preparation method comprises the following steps: dispersing an activating element and a reinforcing phase into tungsten powder through a ball milling method to obtain modified tungsten powder, adding double-granularity composite powder of the modified tungsten powder and unmodified tungsten powder into a forming agent to obtain easily-formed composite powder, and pressing the composite powder into a large-size tungsten copper green body, the method has the characteristics of low cost, good repeatability, controllable process, raw material saving and the like.
