tungstenkarbidiä

Tungstenkarbidi, chemical formula WC, is a chemical compound of tungsten and carbon atoms. It is a hard, brittle, gray-white crystalline solid. Tungsten karbidi is known for its exceptional hardness, which is second only to diamond. It also possesses high stiffness, a high melting point, and good thermal conductivity. These properties make it a valuable material in a wide range of industrial applications.

Tungsten karbidi is typically produced by reacting tungsten powder with carbon black at high temperatures, usually in a furnace. The resulting powder is then consolidated and sintered to form solid parts. Due to its brittleness in its pure form, tungsten karbidi is often mixed with binder metals, such as cobalt or nickel, to improve its toughness and machinability. This composite material, known as cemented carbide or hardmetal, is the most common form used in industry.

The primary use of tungsten karbidi is in the manufacturing of cutting tools, drill bits, and wear parts. Its hardness allows it to maintain a sharp edge at high temperatures and pressures encountered during machining operations. It is also used in mining equipment, ballpoint pen tips, and in the aerospace industry for components that require extreme wear resistance. Despite its strength, tungsten karbidi is susceptible to oxidation at high temperatures in the presence of oxygen.
