Application

Tungsten(IV) carbide is a remarkable material known for its exceptional hardness, which rates at over 9 on the Mohs scale, making it an outstanding choice for cutting and drilling applications. Its unique properties make it an invaluable component in the tool and die industry, where it is employed in crafting cutting tools, sand blasting nozzles, and armor-piercing ammunition, as well as enhancing the traction of tires with added studs. Tungsten carbide's versatility extends beyond these uses, with applications in dental and surgical instruments, wear-resistant coatings, and as a substitute for noble metals in catalysis. In its powdered form, it is produced by heating powdered tungsten with lamp black at 1600°C, resulting in a material stable up to 400°C. Despite its insolubility in water, it is readily attacked by a nitric acid-hydrofluoric acid mixture. Tungsten carbide's adaptability is further enhanced by its combinations with cobalt, where low-cobalt grades are used for high wear resistance and high-cobalt grades are favored for their impact resistance.
