Description
Tungsten Carbide Product Overview
Tungsten carbide (WC) is a dark gray to black powder with a density of about 15.6 g/cm³ and a melting point of about 2870°C. It is roughly twice as stiff as steel and, at about 9 on the Mohs scale, nearly as hard as corundum.
Most tungsten carbide goes into cemented carbide, also called hardmetal. Producers mix WC powder with a metal binder, usually Cobalt, press it and sinter it. The result is the material of cutting inserts, drills, end mills, mining and drilling bits, and wear parts. Small additions of Vanadium Carbide or chromium carbide limit grain growth for fine-grained grades.
Thermal spray companies apply WC-Co and WC-CoCr powders by HVOF to protect components against wear and erosion. Other uses include abrasives, jewelry and radiation shielding. For related materials, see Tungsten Powder and Titanium Carbide.

⚠️ Safety & Handling: Fine powder may irritate the respiratory tract and eyes; dust from mixtures with cobalt is considered a carcinogen by inhalation. Avoid dust formation, use local exhaust ventilation and wear suitable respiratory protection, gloves and eye protection. Store in tightly closed containers in a dry place. Always consult the Safety Data Sheet (SDS) for full classification and handling instructions.
