Military Fragmentation & Ballistics Engineering
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.
Advanced MIM & Pressing Technologies
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.

Frequently Asked Questions
Key technical information for UK engineers and procurement specialists sourcing Tungsten Heavy Alloys.
What are the primary benefits of Tungsten Heavy Alloys (WHA) over lead?
Tungsten heavy alloys offer up to 1.5 times the density of lead (17-18.5 g/cm³ compared to 11.34 g/cm³). WHA provides superior radiation shielding efficiency, allowing for significantly smaller component sizes. Furthermore, unlike lead, tungsten is non-toxic, mechanically stable, and environmentally friendly, meeting strict UK HSE compliance requirements.
Do you supply custom-machined tungsten components to the UK?
Yes, we utilize advanced CNC machining, turning, milling, and Metal Injection Molding (MIM) to manufacture complex, non-standard customized parts. We can deliver high-precision parts based on your engineering drawings (CAD/DXF/STEP) directly to your facilities in the UK.
Which standards do your tungsten heavy alloys comply with?
Our alloys conform strictly to the ASTM B777 and AMS-T-21014 standards, which govern the chemical, physical, and mechanical requirements of high-density tungsten-base materials. Every shipment is accompanied by detailed test reports and chemical analysis certificates.
What is the typical lead time for shipping to the UK?
For standard shapes such as rods, plates, and sheets, we maintain a robust inventory. Custom-machined parts are fabricated in our state-of-the-art facility and typically shipped via air freight (DHL/FedEx/UPS) for quick customs clearance, taking approximately 7 to 14 business days from completion of production to delivery in the UK.
