Tungsten Carbide Description

Tungsten carbide - Wikipedia

Tungsten carbide (chemical formula: WC) is a stone 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 a process called sintering for use in industrial machinery, cutting tools, abrasives ...

Tungsten carbide | stone compound | Britannica

Tungsten carbide, an important member of the class of inorganic compounds of carbon, used alone or with 6 to 20 percent of other metals to impart hardness to cast iron, cutting edges of saws and drills, and penetrating cores of armour-piercing projectiles. Tungsten carbide is a dense, metallike

tungsten carbide description - torencfan.nl

Tungsten carbide is an alloy of elements including tungsten, nickel, tantalum, niobium, titanium and chromium. High quality tungsten carbide, like that used in our Tungsten Forever™ tungsten rings, is composed with a large percentage of tungsten, giving the alloy the inherent hardness and dark-grey color tungsten implies.

US3850614A - Production of tungsten and carbide …

Described herein is the production of tungsten and tungsten carbide in powder form by chemically reducing to tungsten oxide a tungsten compound containing less than 100 ppm total of the elements, sodium, potassium, and calcium, and thereafter chemically reducing the tungsten oxide to tungsten powder with dry hydrogen having a dew point not ...

Tungsten - Wikipedia

The jewelry industry makes rings of sintered tungsten carbide, tungsten carbide/metal composites, and also metallic tungsten. WC/metal composite rings use nickel as the metal matrix in place of cobalt because it takes a higher luster when polished. Sometimes manufacturers or retailers refer to tungsten carbide as a metal, but it is a ceramic.

What is Tungsten Carbide or Hard Metal? - …

2-8-2009 · Tungsten Carbide is often referred to as a Hard Metal due to it’s very high hardness in relation to other metals. Typically a Tungsten Carbide Hard Metal can have a hardness value of 1600 HV, whereas mild steel would be in the region of 160 HV a …

Tungsten Carbide | Knowledge Base Nanomaterials

By varying the cobalt content and the carbide stone size, important properties such as hardness and ductility can be adapted to the desired specification for its application. Tungsten carbide is not self-igniting. As a mixture with air (dust) under the influence of an ignition source, tungsten carbide is possibly flammable (dust explosion).

Tungsten Carbide Powder, Tungsten Carbide …

Description of Cast Tungsten Carbide Powder. Cast tungsten carbide powder is a eutectic mixture of both tungsten carbides, W2C and WC, which has a particularly high degree of hardness and wear resistance. For this reason, it is primarily used in advanced wear protection and tooling technology.

Tungsten Carbide | Definition of Tungsten Carbide …

Tungsten carbide definition is - a compound of tungsten and carbon; especially : a fine very hard crystalline gray powder WC made by heating tungsten or tungsten trioxide with carbon at a high temperature and usually bonded with cobalt or nickel in cemented carbide compositions especially for cutting tools, abrasives, and dies.

Tungsten: Properties, Production, Applications & …

Tungsten carbide is produced either by bonding one tungsten atom with a single carbon atom (represented by the stone symbol WC) or two tungsten atoms with a single carbon atom (W2C). It is done by heating tungsten powder with carbon at temperatures of 2550°F to 2900°F (1400°C to 1600°C) in a stream of hydrogen gas.
