Like tungsten carbide powder (WC powder), ditungsten carbide is also a compound composed of the refractory metal tungsten and the non-metallic element carbon. Its English name is tungsten carbide, with the chemical formula W₂C, and it features a hexagonal close-packed (hcp) crystal structure. Due to slight differences in the crystal structures of WC powder and W₂C powder, their physical and chemical properties, as well as their applications, are also different. Note: The crystal structure of WC can be either a simple hexagonal lattice or a face-centered cubic lattice.

In the complex structure of an automobile, a seemingly minor yet critical component—the counterweight block—plays a vital role. Though small, it is closely linked to the vehicle’s stability and handling, serving as an unsung hero in ensuring driving safety and comfort.

In the vast expanse of cosmic exploration and the graceful flight through blue skies, the aerospace industry demands materials with near-exacting performance standards. From the structural framework of aircraft to the intricate internal instruments, every component must exhibit high strength, low density, high-temperature resistance, and corrosion resistance to ensure safe and stable operation in extreme and hazardous environments. Among these critical materials, high-density tungsten alloy counterweight blocks stand out as unassuming yet indispensable heroes, playing an irreplaceable role in maintaining the balance and stability of flight vehicles.

High-density tungsten alloy, primarily composed of tungsten (typically 85% to 99%) with added metals like nickel, iron, copper, or cobalt, is valued for its high density, strength, corrosion resistance, and wear resistance, making it essential across various fields.
