Tungsten carbide (chemical formula: W C) 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 ...
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 ...
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 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. [1]
Tungsten compounds are often used as industrial catalysts. Its largest use is in tungsten carbide, a wear-resistant metal used in metalworking, mining, and construction. [22] About 50% of tungsten is used in tungsten carbide, with the remaining major use being alloys and steels: less than 10% is used in other compounds. [23]
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]
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.
