TUNGSTEN CARBIDE Meaning and
Definition
-
Tungsten carbide is a hard, dense, and brittle chemical compound that is made up of tungsten and carbon atoms. It is known for its exceptional strength and durability, making it one of the hardest materials available. As a compound, tungsten carbide is commonly represented by the chemical formula WC.
The production of tungsten carbide involves heating tungsten powder with carbon, typically in the form of graphite, at extremely high temperatures. This process creates a gray powder, which can then be pressed and shaped into various forms, including cutting tools, drills, dies, and wear-resistant parts.
Tungsten carbide is valued for its remarkable hardness and resistance to wear and abrasion. It has a high melting point, excellent thermal conductivity, and exceptional strength, making it ideal for use in applications that require a material with outstanding mechanical properties. Tungsten carbide is commonly used in industries such as automotive, aerospace, mining, cutting tools manufacturing, and metalworking.
Due to its outstanding properties, tungsten carbide has become an integral component in a wide range of products, including drill bits, saw blades, machining tools, jewelry, armor-piercing ammunition, and industrial machinery components. It provides increased productivity and efficiency due to its ability to withstand high temperatures, heavy loads, and repeated use without significant wear.
Etymology of TUNGSTEN CARBIDE
The word "tungsten" is derived from the Swedish term "tung sten", meaning "heavy stone". The term was coined by Swedish chemist and mineralogist Carl Wilhelm Scheele in 1781, who discovered the element tungsten. "Carbide" comes from the Latin word "carbo", meaning "coal". It refers to a compound made up of carbon and another element. Hence, "tungsten carbide" refers to a compound of tungsten and carbon, known for its exceptional hardness and strength, often used in industrial applications such as cutting tools and jewelry.
