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 ...
The projectile is double tungsten alloy rod sheathed in low melting point alloy covered with steel, intended to increase penetration against non-explosive reactive armour (NERA) such as Chobham armour. Is slowly being replaced by newer models such as 3BM59/60. Country of origin: Soviet Union; Penetrator dimension: 532 mm 17: 1 L/d; Round weight ...
Some of them, including titanium carbide and tungsten carbide, are important industrially and are used to coat metals in cutting tools. [3] The long-held view is that the carbon atoms fit into octahedral interstices in a close-packed metal lattice when the metal atom radius is greater than approximately 135 pm: [2]
The first cemented carbide developed was tungsten carbide (introduced in 1927) which uses tungsten carbide particles held together by a cobalt metal binder. Since then, other cemented carbides have been developed, such as titanium carbide , which is better suited for cutting steel, and tantalum carbide , which is tougher than tungsten carbide.
Replaced the tool steel core with a tungsten carbide core. It had a red case base including primer, from 1939: red primer only. [6] S.m.K. L'spur [7] Spitzgeschoss mit Kern, Leuchtspur: Has a shorter steel core, and includes a tracer composition. May include color designation such as gelb, German for "yellow".
The jewelry industry makes rings of sintered tungsten carbide, tungsten carbide/metal composites, and also metallic tungsten. [78] WC/metal composite rings use nickel as the metal matrix in place of cobalt because it takes a higher luster when polished. Sometimes manufacturers or retailers refer to tungsten carbide as a metal, but it is a ...
In 1926, Krupp, a German company, developed carbide, a very hard mixture of sintered carbides of various heavy metals, especially tungsten carbide, used for cutting edges and dies. This new material revolutionized metal-removal or “chip-cutting” in manufacturing. In the 1950s, carbide was used in all machining processes except for sawing.
High explosive incendiary/armour piercing ammunition combines a tungsten carbide penetrator with an incendiary and explosive tip. Energy is concentrated by using a reduced-diameter tungsten shot, surrounded by a lightweight outer carrier, the sabot (a French word for a wooden shoe). This combination allows the firing of a smaller diameter (thus ...
