High-Density Tungsten Alloy Supplier from China - ASTM B777 Certified Factory Products
Description
The most important characteristic of tungsten alloys is their high density of 19.25 g/cm³, which is very close to the density of gold (19.3 g/cm³). Tungsten alloy blocks are manufactured from high-quality tungsten alloy materials, with common compositions including tungsten–nickel–iron or tungsten–nickel–copper. The volume of these blocks can be customized according to customer requirements or designed specifically for your needs by our team.
19.25 g/cm³ density, comparable to gold (19.3 g/cm³).
Tungsten–Nickel–Iron (W-Ni-Fe) & Tungsten–Nickel–Copper (W-Ni-Cu).
Tailored volume and design specifications upon request.

Application Fields
These include counterweight components, radiation shielding components, among others. Tungsten alloy blocks are suitable for use in racing cars, aircraft, and sailboats—applications where strict constraints on the volume of counterweight components are required. Tungsten alloys exhibit excellent corrosion resistance and machinability. Tungsten is an environmentally friendly, wear-resistant, and high-hardness material. Due to its density being similar to that of gold, tungsten alloys can be used to manufacture weapon components, molds, and various counterweight components, such as counterweights for speedboats, vehicles, aircraft, helicopters, vessels, and tanks. Thanks to their superior properties—including high density, high melting point, high hardness, high wear resistance, exceptional tensile strength, and high-temperature resistance—tungsten alloys find widespread application across numerous fields. In particular, tungsten alloys possess outstanding radiation absorption capabilities and are now extensively utilized in the medical field.
