　　 Tungsten alloy powder metallurgy It is a process that uses powdered materials—or mixtures of powders, including both metallic and non-metallic powders—as raw materials, which are then formed and sintered to produce solid parts, composites, and various types of components. Powder metallurgy shares similarities with other processes, as it also involves powder sintering; accordingly, many powder‑metallurgy techniques can be applied to the production of such materials. Owing to its advantages, powder metallurgy has become a key solution and plays an important role in the development of our powder‑metallurgy industry.

　　Powder metallurgy of tungsten alloys involves both powders and finished components. The powder‑based processes are, by definition, integral to the metallurgical approach. However, powder‑metallurgy components often extend far beyond the traditional scope of metallurgy, encompassing multiple disciplines—including materials science, mechanical engineering, and mechanics. In particular, modern additive manufacturing technologies, such as powder‑bed 3D printing, seamlessly integrate mechanical engineering, CAD, reverse engineering, layered fabrication, numerical control, physics, and laser technology, transforming powder‑metallurgy parts into sophisticated, multidisciplinary products that span an even broader range of fields.

　　Tungsten alloy powder metallurgy exhibits a unique chemical composition and distinctive mechanical and physical properties that cannot be achieved through conventional casting. By employing powder metallurgy, it is possible to directly produce parts—ranging from semi‑dense to fully dense—with minimal machining, such as planetary bearings, gears, cams, guide rails, cutting tools, and more.

　　(1) Powder metallurgy of tungsten alloys can reduce compositional segregation and eliminate coarse, non‑uniform cast microstructures. It plays a crucial role in the preparation of permanent magnets, hydrogen storage materials, phosphors, catalysts, and high‑temperature superconductors.

　　(2) Tungsten alloy powder metallurgy can produce a series of materials characterized by non‑equilibrium structures and superior electrical, magnetic, optical, and mechanical properties, including amorphous, microcrystalline, quasicrystalline, nanocrystalline, and supersaturated solid solutions.

　　(3) Tungsten alloy powder metallurgy can readily facilitate the fabrication of various types of composites, fully leveraging the unique properties of each constituent phase, and is a cost-effective process for producing composite materials.

　　(4) Tungsten alloy powder metallurgy can produce components with specialized microstructures and properties—such as biocompatible materials, separation membranes, and engineered abrasive tools—that are unattainable through conventional smelting processes.

　　(5) It can be formed almost seamlessly and extensively automated, effectively reducing resource and energy consumption.

　　(6) Ores, tailings, steelmaking sludge, mill scale, and waste can be recycled and reused as Tungsten alloy powder metallurgy Raw materials.
