• Physical properties: Tungsten carbide is a dense, metal-like substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600o C (4,700o F). Tungsten carbide has very high strength for a material so hard and rigid. Compressive strength is higher than virtually all melted and cast or forged metals and alloys; and is two to three times as rigid as steel and four to six times as rigid as cast iron and brass. High resistance to deformation and deflection is very valuable in those many applications where a combination of minimum deflection and good ultimate strength merits first consideration. For such a hard material with very high rigidity the impact resistance is high because it is in the range of hardened tool steels of lower hardness and compressive strength. It also performs well up to about 1000°F in oxidizing atmospheres and to 1500°F in non-oxidizing atmospheres; it undergoes no phase changes during heating and cooling, retains its stability indefinitely; and retains toughness and impact strength in the cryogenic temperature ranges. (-453°F.) Tungsten carbide has exceptional resistance to galling and welding at the surface, and has sufficient resistance to corrosion-wear conditions for many applications. Tungsten carbide wears up to 100 times longer than steel in conditions including abrasion, erosion and galling. Wear resistance of tungsten carbide is better than that of wear-resistance tool steels.

It is used extensivly in the tool and die industry for drilling and cutting tools, sand blasting nozzels, armor-piercing bullets, and studs to increase traction of tires. Besides, it is used in dental burs, surgical instruments, wear-resistant coatings; in manufacture of cemented carbide; Substitute for noble metals in catalysis. Tungsten Carbide/Carbon (WC/C) is a black-gray colored coating of hard tungsten carbide particles in a soft amorphous carbon matrix. It is used for precision components with abrasive and adhesive wear, seizure problems (poor lubrication) and for dry machining applications. Tungsten carbide is extensively used as a cutting tool for machining and in armor-piercing ammunition. It is also used in farriery, the shoeing of horses as well as to improve traction on slippery surfaces like roads or ice. It finds application in nuclear reactors as an effective neutron reflector. It is also used for making surgical instruments meant for open surgery such as scissors, forceps, hemostats, blade-handles and in laparoscopic surgery instruments such as graspers, cutter, needle holder and cautery. Further, it also used to make the rotating ball in the tips of ballpoint pens, bridal jewelry, and gauge blocks, which is useful for producing precision lengths in dimensional metrology.
