Chemical Properties

Gray powder. Mohs hardness of 9+ in solid form. Insoluble in water but readily attacked by a nitric acid– hydrofluoric acidmixture. Stable to 400C with chlorine, burns in fluorine at room temperature, oxidizes on heating in air.

Uses

Tungsten carbide is extremely hard and are excellent cutting materials. 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.

Uses

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.

Definition

A black powder,WC, made by heating powderedtungsten metal with lamp black at1600°C. It is extremely hard (9.5 onMohs’ scale) and is used in dies andcutting tools. A ditungsten carbide,W2C, also exists.

Definition

A ditungsten carbide, W2C, with similar physical properties is also known. WC is said to be the strongest of all structural materials.

Hazard

Toxic by inhalation.

Industrial uses

Tungsten carbide with a 3 to 20% matrix ofcobalt is the most common structural RHM. Thelow-cobalt grades are used for applicationsrequiring wear resistance; the high-cobalt gradesserve where impact resistance is required.

Safety Profile

Chronic inhalation causes lung damage in humans. Ignites at 600°C in nitrogen oxide atmospheres. Violent reaction with F2, ClF3, NOx, IF5, PbO2, NO2, N20. See also TUNGSTEN COMPOUNDS.
