Cemented Carbide is an alloy made from sintered hard metallic carbide powder, and is simply called Hard metal, which is used in making hard metal tools. Generally, it means sintered mixture of Tungsten carbide WC and Cobalt Co as binder. The material is used in
Cemented tungsten carbide, Cemented WC, Hard metal Note The tungsten carbide WC content is generally 85-95 amp the cobalt content is generally 5-15. 1 85 WC, 15 Co 2 92 WC, 8 Co 3 78 WC, 14 Co, 8 Ti A mixture of tungsten carbide, cobalt, and sometimes other metals amp metal oxides or carbides.
WCCo-Crushed cemented carbide CSC is manufactured from used tooling that is comprised of micron sized WC bound by cobalt. Surface Engineering CSC is crushed from straight grade stock to ensure the wettability of the particles during application. During crushing, these particles yield two shapes, blocky and non-blocky flats and slivers.
Jul 09, 2014 Carbide Technologies Inc. MSDS Cemented Carbide Product with Cobalt Binder NFPA OSHA PICTOGRAMS PERSONAL PROTECTION EQUIPMENT 1 0 0 Section 11, Toxicological information Cobalt The International Agency for Research on Cancer IARC lists Cobalt metal with tungsten carbide as a Group 2A carcinogen Probably Carcinogenic to Humans.
The carbide phase is generally between 70 and 97 of the total weight of the composite. Its grain size averages between 0.4 and 10 m. Tungsten carbide WC, the hard phase, together with cobalt Co, the binder phase, forms the basic cemented carbide structure from which other types of cemented carbide have been developed.
Cemented carbide sintered articles, when used under normal conditions, do not present hazards that require accidental release measures. Wet or dry grinding of cemented carbide products may release dust or mist of potentially hazardous ingredients. Avoid inhaling, swallowing or allowing to come in contact with skin and eyes.
Nov 18, 2019 The tungsten carbide is very high in hardness and the cemented carbide material hardness is reduced with increasing amounts of relatively soft cobalt binder 330 Hv, in this case about 20. With super high speed steel the iron matrix itself is hardened to 68-72 Rc but there is also some content of vanadium carbide 2800 Hv and molybdenum ...
Dec 07, 2020 In terms of cemented carbides used in wear protection and cutting tool applications, tungsten carbide often acts as the hard carbide phase and cobalt
A rock bit employs cemented tungsten carbide inserts for engaging a rock formation for drilling oil wells or the like. The cemented tungsten carbide inserts have as a binder phase a cobalt base alloy including from 10 to 35 by weight nickel, from 3 to 10 by weight chromium, from 1 to 6 by weight of molybdenum, and a balance primarily of cobalt.
the linear thermal expansion of tungsten carbide-cobalt mixtures con taining approximately 6 and 13 percent of cobalt. These mixtures are called cemented tungsten carbide or Oarboloy in the United States and Widia in Germany. Data on the thermal expansion of cemented tungsten carbide, which is used in industry, should be available.
Such cemented carbide compositions can be employed as tooling in a variety of applications including earth boring and mining operations as well as machining various metals and alloys. For example, a sintered cemented carbide composition described herein comprises a hard particle phase including tungsten carbide and a cobalt-based metallic ...

May 22, 2019 Carbide is made by the method of powder metallurgy from the refractory metal hard compound and the metal bonding phase. The commonly used hard compounds are carbides. As the hard alloy for cutting tools, commonly used WC, TiC , TaC, NbC, etc., the binder is Co, and the strength of the cemented carbide mainly depends on the content of Co.
Property of tungsten cobalt cemented carbide depends on the content of cobalt and crystalline grain of tungsten carbide. The hardness, strength and toughness of cemented carbide will rise obviously wh...
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 ...
Nov 01, 2018 Cemented tungsten carbide materials are traditionally bonded using a cobalt matrix, resulting in a material that possesses a unique combination of exceptional properties. However, cobalt has been recently classified as reasonably anticipated to be a human carcinogen, and thus, removal of this hazardous phase is desired for many applications.
May 26, 2020 However, considering the hardness of cemented carbide, especially the higher bond grade with 25 cobalt binder and coarser grain structure, it shows surprisingly high impact strength. The transverse fracture strength TRS is usually mistaken as an index to evaluate the impact resistance of cemented carbide.
Apr 01, 2019 In 1927 the German company Friedrich Krupp marketed worldwide the first cemented carbide composed of tungsten carbide and cobalt WC-Co under the name WIDIA an acronym for the German words WIe DIAmant like diamond. They were primarily used as materials for wire drawing dies and wear resistant parts.
The crystal structure includes tungsten carbide and cobalt. Tungsten carbide based cemented carbides pertain to a ternary WCoC system. In this context, the chapter discusses the relevant binary phase diagrams viz WC, CoC, and CoW. Phase equilibria in ternary systems of transition metals and carbon are determined by the ...
