High-performance tungsten heavy alloy solutions designed for extreme impact, ballistic protection, and defense counterweight systems.
In the theater of modern military engineering, the demand for materials that offer extreme density, unmatched hardness, and exceptional thermal stability has never been more critical. Tungsten Heavy Alloys (WHAs) have emerged as the primary material of choice, particularly for the manufacturing of tungsten alloy shafts used in kinetic energy penetrators (KEPs) and armor-piercing munitions. Historically, depleted uranium (DU) was favored for its self-sharpening properties during penetration. However, due to environmental, radiological, and geopolitical concerns, the global defense sector has systematically transitioned toward tungsten heavy alloys.
The commercial market for defense-grade tungsten has experienced a significant surge. This growth is driven by the modernization of main battle tanks, the development of hypervelocity railgun technologies, and the rise of advanced anti-missile defense systems. Today, tungsten alloy shafts are manufactured to withstand the extreme stresses of high-velocity launches (often exceeding Mach 5) and the brutal energy transfer required to defeat modern explosive reactive armor (ERA).
"The shift from depleted uranium to high-density tungsten heavy alloys represents a technological milestone in clean, sustainable, yet lethally effective defense manufacturing."
With densities ranging from 17.0 to 18.8 g/cm³, WHAs concentrate massive kinetic energy into a minimal cross-sectional area, maximizing penetration depth.
Prevents structural failure, bending, or premature shattering of the shaft during launch acceleration and initial impact phase.
Withstands the extreme friction-induced temperatures generated during atmospheric transit and armor penetration.
The primary application of long-rod tungsten alloy shafts is in APFSDS rounds, commonly referred to as "dart ammunition." These projectiles rely purely on kinetic energy rather than explosive chemical energy to defeat heavy tank armor. The penetrator rod must feature an extremely high length-to-diameter (L/D) ratio. The structural integrity of this rod is paramount; any bending during flight or impact reduces penetration capabilities. Zhuzhou Jiuding's specialized swaging and sintering techniques ensure that our tungsten alloy shafts possess the straightness, concentricity, and microstructural homogeneity required for modern sub-caliber munitions.
In air defense and anti-ballistic missile systems, kinetic kill vehicles utilize tungsten alloy cores to destroy incoming targets through sheer impact force. By placing high-density tungsten shafts at the core of the interceptor, engineers can maximize the impact footprint and guarantee the destruction of structural components, engines, or chemical payloads within the target missile.
Electromagnetic railgun systems accelerate projectiles to speeds exceeding Mach 6. At these velocities, traditional metals melt or deform due to electromagnetic drag and atmospheric friction. Tungsten alloy shafts, combined with specialized binding matrices, offer the necessary electrical conductivity, ultra-high melting point, and mechanical strength to survive electromagnetic launch forces and deliver devastating impact energy at extreme ranges.
Integrating state-of-the-art metallurgical science to control fragmentation and penetration mechanics.
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.

As armor designs evolve, incorporating complex composite ceramics and active protection systems (APS), the metallurgical design of the tungsten alloy shaft must evolve in parallel. Industry research is currently focused on three major development fronts:
By refining the grain size of tungsten within the nickel-iron matrix down to the sub-micron or nano-scale, researchers can dramatically increase the yield strength and toughness of the alloy. This prevents the shaft from fracturing prematurely when encountering angled or multi-layered reactive armor, allowing the rod to maintain its structural integrity for deeper penetration.
Historically, depleted uranium (DU) had a distinct advantage over tungsten: during penetration, DU undergoes localized adiabatic shear banding, causing the sides of the tip to peel away and maintain a sharp point ("self-sharpening"). Traditional tungsten alloys tend to "mushroom," which increases the resistance area and limits penetration. Modern research in tungsten alloy shaft manufacturing involves introducing metallic glass matrices or specific fiber reinforcements to induce similar adiabatic shear failures, giving tungsten alloys the same self-sharpening efficiency without the radiological hazards.
For guided kinetic energy projectiles, complex aerodynamic control surfaces and internal channels for sensors are required. Traditional machining of tungsten is highly challenging due to its hardness. Advanced Metal Injection Molding (MIM) technologies allow for the net-shape production of intricate tungsten alloy components, significantly reducing production costs while maintaining the high density and structural integrity required for modern defense hardware.
