Jan 30, 2018· Published on Jan 29, 2018 Cemented carbide is a metal matrix composite consisting of hard phase and binder metal hard phases use refractory metal carbide (commonly tungsten carbide）or ceramic phase
For grades containing only tungsten carbide and a binder metal, the density of the composite decreases as the lighter binder metal content increases. [ASTM B-311; ISO 3369] Hardness is the resistance of a cemented carbide to penetration by a diamond indenter under a specific load.
However, one of the newest applications for tungsten carbide that is gaining popularity every day for making jewelry. Naturally, the hardness of carbide makes it an attractive alloy to use for crafting rings, pendants, earrings, and other jewelry, but when cut and polished correctly, the material is actually stunningly beautiful as well.
This results in precipitation hardening of the binder phase. Additions of Ru, Re, and Os increase the hardness, and bend, compression and yield strengths, of WC ― Co alloys. Examples of the successful use of WC ― Co cemented carbide tools alloyed with noble metals for the machining of heat-resistant alloys and high-alloy steels are given.
Carbide inserts are utilized to enhance the execution of machining applications, for example, machining of hard materials and difficult to machining materials like titanium alloys. The surface roughness (Ra) and tool wear forecast assume a huge part of machining for a long time arranging and control of machining parameters and enhancement of cutting conditions.
Federal Carbide offers a complete family of standard Ni-bonded tungsten carbide grades for applications requiring resistance to corrosion.In addition, Federal has developed numerous custom grades for use in extremely corrosive environments, in situations demanding both high toughness and corrosion resistance, and where strict food processing equipment requirements must be met.
Received: 30 January 2018; Accepted: 7 March 2018; Published: 9 March 2018 Abstract: Interfaces between alloys simulating binders in WC-Co cemented carbides and tungsten carbide were examined on the micro-, nano-, and atomic-scale. The precipitation of fine WC grains and -phase occurs at the interface of the alloy with the low carbon content.
Taking into account that the state-of-the-art broaching process is working with high-speed-steel tools, the higher thermal resistant cemented carbide cutting materials offer the potential to significantly increase cutting speeds, which lead to increased process productivity.
Feb 07, 2009· 13 Jan 09 11:01. Thanks for the replies, and sorry for any lack of clarity here. I want a solid metal/alloy here, NOT a composite, cemented carbide, coating, plating, or other. I know people will want to mention these options, and they are interesting, but not what I'm asking.
Cemented carbide is a hard material used extensively as cutting tool material, as well as other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. Mentions of ...
High-frequency induction brazing of cemented carbide (WC–Co, K20) and alloy steel (AISI 4140) using Cu–Zn base filler metal was carried out. The relationship between microstructure and performance of the welding joint was investigated. It was found that the filler metal exhibited excellent wettability and metallurgical bond in the welding surface.

Alibaba offers 15,196 tungsten cobalt alloy products. About 4% of these are tool parts, 1% are other metals & metal products, and 1% are cemented carbide. A wide variety of tungsten cobalt alloy options are available to you, such as free samples, paid samples.
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. This material, which belongs to the class of superhard materials, is used extensively in cutting tools.
Extensive and rigorous wear tests involving the failure criterion were carried out initially on (i) TiC coated and (ii) uncoated cemented tungsten carbide, and (iii) cemented titanium carbide (also known as solid TiC). The studies revealed that solid TiC was the best tool for turning steel followed closely by TiN coated tungsten carbide.
Cemented carbide innovated cutting work by achieving steel cutting speeds of 100 to 150 m/min, approximately four times the cutting speeds of high-speed steel (20 to 40 m/min). In 1928, Sumitomo Electric Industries, Ltd. succeeded in the test production of a cemented carbide History of Development of Cemented Carbides and Cermet Keiichi TSUDA
