Cemented carbide is a powdery metallurgical material; a composite of tungsten carbide (WC) particles and a binder rich in metallic cobalt (Co). Cemented carbides for metal cutting applications consist of more than 80% of hard phase WC. Additional cubic carbonitrides are other important components, especially in gradient sintered grades.

Tungsten cemented carbide products are widely used in cutting tools for machining, ammunition, mining, nuclear, sports, surgical instruments, jewelry and others. Carbide ball is widely used to make the rotating ball in the tips of ballpoint pens.

as cemented (or sintered) carbides, or simply as tungsten carbides. Cobalt–tungsten carbide hard metals are composites of tungsten carbide particles (either tungsten carbide alone or in combination with smaller amounts of other carbides) with metallic cobalt powder as a binder, pressed into a compact, solid form at high temperatures by a process

Cemented Carbide Application. Cemented carbide ( tungsten carbide ) is widely used as cutting tool materials, such as turning tools, milling cutters, planers, drills, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone materials, and ordinary steel, as well as for cutting heat-resistant steel, stainless steel, high manganese steel ...

Cemented Carbides get their hardness from the Tungsten Carbide grains and their toughness from the bonding produced by the cementing action of the Cobalt metal. By varying the amount of Cobalt we can change the hardness, wear resistance, and toughness (shock or impact resistance) of the carbide to provide optimum performance for your specific ...

Cemented carbides combine the high hardness and strength of metallic carbides (WC, TiC, TaC) or carbonitrides (eg TiCN) with the toughness and plasticity of a metallic alloy binder (Co, Ni, Fe), in which the hard particles are evenly distributed to form a metallic composite. Tungsten carbide is the most metallic of the carbides, and by far the ...

Cemented carbides are manufactured by the unique method, called powder metallurgy. It is the method of making forms by sintering the pressed powder. As tungsten carbide (WC), mainly used in cemented carbides, is very …

Cemented carbides are metal composites that represent the most widely-known powder metallurgy product. The microstructure of cemented carbides consists of a higher portion of tungsten carbide (WC) and possibly smaller portions of titanium and tantalum carbides, mutually linked to a binder phase that is cobalt (Co).

Cemented tungsten carbide is one of the most widely produced powder metallurgy products. For the past 75 years cemented tungsten carbide tools have been performing at an increasingly popular rate. Fine-grain, especially nano-grain, cemented tungsten carbides make it possible to achieve a new range of properties that are improved

Tungsten, molybdenum, and cemented carbide parts can be produced using several additive manufacturing technologies. This article classifies the most relevant technologies into two groups based on the raw materials used: powder-bed methods, such as selective laser melting, electron beam melting, and binder jet three-dimensional (3-D) , and feedstock methods, such as …

cemented carbides allows improvement of their high-temperature properties [4–10]. Cemented carbides containing rhenium were first patented in 1949 [3]; however, at this time no information regarding potential ad-vantages of partial substitution of Co by Re in the cemented carbide binder for high temperature applications was available.
