  2. Cemented carbide - Wikipedia

    en.wikipedia.org/wiki/Cemented_carbide

    Mentions of "carbide" or "tungsten carbide" in industrial contexts usually refer to these cemented composites. Most of the time, carbide cutters will leave a better surface finish on a part and allow for faster machining than high-speed steel or other tool steels. Carbide tools can withstand higher temperatures at the cutter-workpiece interface ...

  3. Drill bit - Wikipedia

    en.wikipedia.org/wiki/Drill_bit

    An insert of tungsten carbide is brazed into the steel to provide the cutting edges. Masonry bits typically are used with a hammer drill , which hammers the bit into the material being drilled as it rotates; the hammering breaks up the masonry at the drill bit tip, and the rotating flutes carry away the dust.

  4. Tungsten carbide - Wikipedia

    en.wikipedia.org/wiki/Tungsten_carbide

    Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering [7] for use in industrial machinery, engineering facilities, [8] molding blocks, [9] cutting tools, chisels, abrasives, armor ...

  5. Carbide - Wikipedia

    en.wikipedia.org/wiki/Carbide

    Boron carbide, B 4 C, on the other hand, has an unusual structure which includes icosahedral boron units linked by carbon atoms. In this respect boron carbide is similar to the boron rich borides. Both silicon carbide (also known as carborundum) and boron carbide are very hard materials and refractory. Both materials are important industrially.

  6. Tool bit - Wikipedia

    en.wikipedia.org/wiki/Tool_bit

    Originally, all tool bits were made of high carbon tool steels with the appropriate hardening and tempering.Since the introductions of high-speed steel (HSS) (early years of the 20th century), sintered carbide (1930s), ceramic and diamond cutters, those materials have gradually replaced the earlier kinds of tool steel in almost all cutting applications.

  7. End-face mechanical seal - Wikipedia

    en.wikipedia.org/wiki/End-face_mechanical_seal

    The seal ring and mating ring are sometimes referred to as the primary sealing surfaces. The primary sealing surfaces are the heart of the end-face mechanical seal. A common material combination for the primary sealing surfaces is a hard material, such as silicon carbide, ceramic or tungsten carbide and a softer material, such as carbon. Many ...

  9. Unified numbering system - Wikipedia

    en.wikipedia.org/wiki/Unified_numbering_system

    The Unified Numbering System for Metals and Alloys (UNS) is an alloy designation system widely accepted in North America.Each UNS number relates to a specific metal or alloy and defines its specific chemical composition, or in some cases a specific mechanical or physical property.
