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 ...
Tungsten's desirable properties such as resistance to high temperatures, its hardness and density, and its strengthening of alloys made it an important raw material for the arms industry, [54] [55] both as a constituent of weapons and equipment and employed in production itself, e.g., in tungsten carbide cutting tools for machining steel. Now ...
The discovery of superhard tungsten tetraboride is further evidence for the promising design approach of covalently bonding incompressible transition metals with boron. While WB 4 was first synthesized and identified as the highest boride of tungsten in 1966, [52] it was only recognized as an inexpensive superhard material in 2011. [53]
Tungsten carbide end mills. The carbides of the group 4, 5 and 6 transition metals (with the exception of chromium) are often described as interstitial compounds. [2] These carbides have metallic properties and are refractory. Some exhibit a range of stoichiometries, being a non-stoichiometric mixture of various carbides arising due to crystal ...
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 ...
A very important product of this type is tungsten carbide. [1] Tungsten carbide is used to cut and form other metals and is made from tungsten carbide particles bonded with cobalt. [2] Tungsten carbide is the largest and most important use of tungsten, [3] consuming about 50% of the world supply. [4]
