Tungsten Diboride (WB2) Powder CAS 12007-10-2

Tungsten Diboride (WB2) is an ultra-high-performance ceramic material renowned for its exceptional hardness, thermal stability (melting point >2800°C), and metallic conductivity. This dark gray crystalline compound is engineered for extreme environments, combining the refractory properties of tungsten with boron’s hardness-enhancing capabilities. Ideal for aerospace, nuclear, and industrial applications requiring unmatched durability under high stress and temperature.

Ultra-High Hardness: Surpasses traditional carbides and borides in abrasive environments.
Thermal Shock Resistance: Stable under rapid temperature fluctuations (e.g., 20°C to 2000°C).
Oxidation Resistance: Forms protective WO₃/B₂O₃ layers above 800°C in air.
Heavy-Duty Performance: Ideal for extreme pressure and wear conditions.
