Engineered for high-precision machinery, electrical discharge machining, and advanced industrial applications.
Pure tungsten, known for its extraordinary physical properties including the highest melting point of any metal (3,422°C), a density comparable to gold (19.3 g/cm³), and exceptional thermal conductivity, has transitioned from a specialized niche material to a cornerstone of modern high-tech manufacturing. The global industrial landscape demands components that can withstand extreme thermal loads, aggressive chemical environments, and mechanical stress without losing dimensional stability. Consequently, machining pure tungsten has become a vital capability for sectors like aerospace, semiconductor manufacturing, nuclear energy, and high-precision electrical discharge machining (EDM).
“As high-precision machinery systems operate under increasingly severe conditions, the choice of refractory metals like pure tungsten determines the structural limits of next-generation technology.”
Electrical Discharge Machining (EDM) relies on the controlled erosion of material through electrical discharges (sparks) between an electrode and the workpiece. The performance of the electrode is the single most critical factor in determining the accuracy, speed, and surface finish of the machined part. Pure tungsten and its alloys are the gold standard for EDM electrodes because of their incredible resistance to spark erosion. In micro-EDM and high-precision tooling, standard copper or graphite electrodes wear down too quickly, leading to dimensional inaccuracies. Pure tungsten electrodes maintain their sharp profiles and structural integrity under high electrical currents, enabling manufacturers to achieve tolerances in the sub-micron range.
Withstands temperatures up to 3422°C without structural deformation, vital for high-energy EDM processes.
Maintains sharp edges and profiles during micro-machining, ensuring perfect geometry in finished parts.
Low spark wear rates mean fewer tool changes, faster cycle times, and reduced manufacturing costs.
Beyond EDM, machined pure tungsten components are critical in high-precision machinery. In the semiconductor industry, pure tungsten parts are utilized in ion implantation chambers where they must resist high-energy ion beams and extreme vacuum conditions. In medical technology, tungsten’s high density makes it the premier material for collimators and radiation shielding components in CT scanners and oncology treatment devices. The aerospace sector relies on machined tungsten for structural balance weights, vibration dampening systems, and high-temperature nozzles where standard alloys would fail catastrophically.
Pre-control use of shell fragments groove, groove or increase the lining of explosives and other technical measures to make the shell partial reduction of the intensity to control the explosion of the broken parts to form fragments. Such warheads are characterized by the formation of fragment size of the uniform, shape the ground rules.
Prefabricated fragments forming a pre-processing will be the shape and quality of pre-designed steel ball, steel arrows, tungsten ball, tungsten and other prefabricated column fragments produced prefabricated sets of body fragments, and installed in the grenade projectile outer surface or inner surface. These prefabricated projectile fragmentation grenade explosion with the formation of fragments together constitute the natural fragmentation field, due to resistance of prefabricated fragments flying characteristic consistency, with prefabricated fragments of the grenade will be set within the framework of the lethal effect of a relatively dense, full-bombs a greater degree of lethality increase.
Because there is a prefabricated fragments will affect the negative effects of missile body structures, usually only in low-pressure chamber which uses artillery and ammunition, such as the forced large-caliber bullets and grenades. Applications also are the most common aircraft shells, grenades, mines and so on. The current high chamber pressure prefabricated artillery fragments, are used in canister form, such as Switzerland, L70-type 40 mm grenade where overhead is filled with tungsten carbide ball. Prefabricated fragments technology has been widely used on all types of warheads. Cylindrical fragments (Tungsten column) as a type of prefabricated fragments, due to high density, armor-piercing capability, as air defense, anti-radiation, anti-surface, one of the main anti-elements, and widely used.

Despite its outstanding advantages, pure tungsten is notoriously difficult to machine. Due to its high hardness, low ductility at room temperature, and tendency to chip or crack, traditional machining methods often result in rapid tool wear and poor surface finish. To overcome these limitations, advanced machining facilities employ specialized techniques:
The future of machining pure tungsten lies in micro-manufacturing and hybridization. As micro-electromechanical systems (MEMS) and advanced aerospace components shrink in size, the demand for micro-EDM electrodes made of high-purity tungsten is growing exponentially. Furthermore, research is actively exploring the integration of additive manufacturing (3D printing) with post-process precision machining. This hybrid approach allows for the creation of complex, internal geometries in tungsten parts (such as conformal cooling channels in EDM electrodes) that were previously impossible to manufacture, opening up new horizons for thermal management and tool longevity.
