Discover our highly machinable, high-density tungsten components designed for premium fishing gear and sports applications.
Over the last decade, the global sporting goods and outdoor recreation markets have undergone a major paradigm shift toward environmental sustainability. Historically, lead has been the go-to material for weights, sinkers, and counterbalances due to its high density and low cost. However, lead's severe environmental toxicity has prompted strict regulations worldwide, leading to bans on lead-based tackle in various jurisdictions across North America and Europe.
This regulatory landscape has accelerated the demand for high-performance, non-toxic alternatives. Machinable tungsten heavy alloy (WHA) has emerged as the premier candidate. Boasting a density nearly 1.7 times greater than lead, tungsten alloys allow for significantly smaller profiles without sacrificing weight. This unique physical property offers unmatched benefits in both competitive angling and professional sports design.
Pure tungsten is notoriously difficult to process; its extreme hardness and brittleness make traditional machining methods highly inefficient. By alloying tungsten with binders such as nickel, iron, or copper, manufacturers create a material that retains tungsten's high-density benefits while drastically improving its machinability. This allows for complex geometries, precise threading, and customized configurations crucial for advanced sports equipment and micro-fishing gear.
100% lead-free, non-toxic composition ensures compliance with global environmental regulations, protecting aquatic ecosystems and wildlife habitats.
With densities ranging from 17.0 to 18.8 g/cm³, tungsten components deliver compact mass distribution, reducing drag and increasing sensitivity.
From deep-water angling to Olympic-level sports equipment, machinable tungsten alloys are redefining performance standards.
In the sport of angling, sensitivity is everything. Machinable tungsten alloy fishing sinkers, jig heads, and custom lures provide a distinct competitive edge. Because tungsten is much harder than lead, it does not absorb sound or vibration. When a tungsten sinker makes contact with rocks, gravel, or timber on the lake bed, it transmits a distinct acoustic signal up the line, allowing anglers to feel the difference in bottom composition and detect even the most subtle fish bites.
Furthermore, the high density allows for a smaller physical profile. A tungsten sinker is roughly 30% smaller than a lead weight of equivalent mass. This reduced size minimizes water resistance, resulting in faster sink rates, cleaner casts, and significantly fewer snags in heavy cover or vegetation.
In high-performance sports, weight distribution directly influences dynamic balance, speed, and accuracy. Machinable tungsten alloys are utilized across various athletic disciplines:
Established in 2001, Zhuzhou Jiuding Metal Technology Co., Ltd is a professional joint venture company which engages in manufacturing, machining and sales of tungsten heavy alloy, tungsten copper, cemented carbide, pure tungsten and other relevant tungsten alloy products. Our products mainly include tungsten heavy alloy, tungsten carbide, tungsten alloy fishing sinker, tungsten darts, tungsten Alloy swaging rod, bucking bar, copper tungsten electrode, tungsten alloy bullets, tungsten alloy syringe, tungsten alloy shielding vial, tungsten alloy boring bar, etc. Due to its characteristics of high density, high hardness, high melting point, anti-corrosion, radiation protection, non-toxic and environmental-friendly, therefore, our Fragmentation is a natural under the action of detonation products, the shell expansion, fracture broken is made of such warheads is characterized not only as a container shell to form another anti-elements, fragments the size of the shell is uneven, irregular shape in the air fast decay in flight speed, so that the effective anti-personnel grenade limited in scope.
Combining state-of-the-art metallurgical technologies with precision machining processes.
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.
Tungsten alloy products are widely used in fields of aerospace, medical equipments, military, mechano-electronic, oil exploration, vehicle, sports counterweight, gold-plated jewelry etc. With strong funding, advanced manufacturing technology, strict quality control and technical support from national famous university, our products are popular in country of America, Canada and Japan etc. Besides, we own international advanced technology of Metal Injection Molding (MIM) and pressing technology, we can manufacture standard products and various non-elevation products.
As sustainability regulations tighten worldwide, the market for eco-friendly fishing tackle and sports equipment is experiencing rapid growth. Manufacturers that proactively transition to machinable tungsten alloys are positioning themselves as industry leaders. Beyond meeting environmental standards, the adoption of tungsten alloys allows brands to market premium, high-performance products that command higher margins.
From a manufacturing standpoint, the integration of Metal Injection Molding (MIM) and automated CNC machining has drastically reduced production waste and cycle times. What was once a costly, specialized material is now highly viable for mass production. This technological evolution ensures that high-density tungsten alloys will remain the standard for premium sporting goods, industrial counterweights, and sustainable outdoor gear for decades to come.
