Tungsten Carbide Uses Properties

Tungsten Carbide Uses Properties Tungsten carbide is a compound composed of tungsten and carbon with a molecular formula of WC and a molecular weight of 195.85. Due to its excellent physical and chemical properties, tungsten carbide has been widely used in the industry and our everyday life.

Applications of Graphite

Our range of products include graphite for glass, graphite moulds for diamond and tungsten carbide tool, graphite powder, graphite for aluminum, brass and copper extrusion casting, graphite for jewellery and graphite. In the glass industry, Graphite Material for Glass Beads,Tubes and Glass Apparatus are used to meet the various challenges of glass melting and molding, and of transporting hot

* Diamond and Tungsten Carbide Tool Manufacturers

Graphite Moulds are used in manufacture of Diamond Tools and Tungsten Carbide Tools. Hot pressure sintering involves heating of diamond segments under very high pressure with help of graphite mould. Our range of of graphite grades combine properties like Hardness, Resistivity and Flexural strength for this application.

Graphite

The graphite market is is far larger than the markets for magnesium, molybdenum cobalt, tungsten, lithium and rare earths combined. There are many high temperature uses for graphite in the chemical industry such as in the production of phosphorus and calcium carbide in arc furnaces.

J M Diamond Tool: PCD and CBN Information

This PCD diamond layer is then bonded to a tungsten carbide substrate, which provides strength and a brazable base to permit bonding to other metals. Polycrystalline tipped tools are exceptionally resistant to wear compared to tungsten carbide or ceramic tools.

Frictional performance of silicon carbide under different lubrication conditions

carbide is commonly used in hard rings because of its abrasion resistance, corrosion resistance, and thermal shock resistance. In this study, the frictional performance of silicon carbide, including graphite-added silicon carbide, under water and lubrication-absent

The main products are high purity graphite products, various kinds of graphite moulds, sheathes and linings, graphite grains etc. In 2003, we set up Elite Sight Limited sharing the import and export knowledge gained by Sun King Hing Company, this limited liability company will mainly responsible for the USA and European market.

Master Group

A critical review on the chemical wear and wear

2020/1/14Take the graphitization of diamond as an example: Although diamond and graphite are all carbon allotropes, graphite is more stable than diamond [], from an energy standpoint. Under regular catalysis, there is a tendency to transform to a more stable lamellar graphite

Materials used in building the mold include, sand, graphite, ceramic, clay, other refractory materials, plastic, rubber and wax. Once the mold is formed, powdered steel or tungsten carbide is poured into the mold and is cured by press molding or infiltrating with a binder forming a bit body.

China Tungsten Carbide manufacturer, Boron Carbide,

Zhuzhou Good Cemented Carbide Co., Ltd. Was established in the Chinese largest tungsten carbide producing area, Zhuzhou City, Hunan Province. The factory is equiped with ball mills, presses, sintering furnaces, vacuum sintering furnaces, coreless grinding, tool grinding, wire cutting, sand blasting machines, high-precision grinding machines and other production equipments.

Why Tungsten Carbide Is Widely Used As Tool Material

Wide applications of tungsten carbide Tungsten carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drills, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and

Covalent Crystals

Tungsten carbide (WC) is probably the most widely encountered covalent solid, owing to its use in carbide cutting tools and as the material used to make the rotating balls in ball-point pens. It has a high melting point (2870 C) and a structure similar to that of diamond, although it is slightly less hard.

Engineered Materials

If you have a need for a part custom machined from carbon-graphite, alumina ceramic, silicon carbide, tungsten carbide or other technical ceramics, Gaddis is your source! Our products are used primarily in rotating applications such as pumps, compressors, industrial mixers and mechanical seals.

Bonding a diamond compact to a cemented carbide

Cemented carbide substrates are known in the art and comprise a mass of carbide particles, for example, tungsten carbide particles, bonded into a hard, coherent form by means of a binder metal such as cobalt, iron, nickel or an alloy containing one or more of

Interlayers for the diamond coating

Diamond-coated carbide tools are eminently suitable for machining graphite, fiber-reinforced plastics and aluminum alloys. At the Fraunhofer IST interlayers are being developed as alternatives to a process which has to date been essential: etching pretreatment of the cemented carbide base body.
