The Designer's Guide to Tungsten Carbide is your goto source for the basics of tungsten carbide tooling from properties to finishing techniques. www. 3 ... sintering, and sintering techniques are among the factors influencing the characteristics of the
Form of Tungsten. This is a function of the raw material cost and of the amount of work involved in producing the finished product. A broad range of prices for finished tungsten products would be from 25 to 2500 per kilo, with the majority of products in the 100 to 350 per kilo range.
Tungsten Carbide is a chemical compound containing equal parts of Tungsten and Carbon. In it's most basic form, Tungsten Carbide is a gray powder, but it can be pressed and formed into shapes. In it's most basic form, Tungsten Carbide is a gray powder, but it can be pressed and formed into shapes.
At Total Carbide we offer, as standard, a full range of Tungsten Carbide Grades. We would be happy to assist in grade selection. For unique applications, special materials can be developed and manufactured to suit product requirements.

May 30, 2019· A method for bonding a cemented or sintered tungsten carbide element to a structural component is provided comprising cladding at least one surface of the cemented or sintered tungsten carbide element with a metal layer using hot isostatic pressing; and friction welding a cladded surface of the cemented or sintered tungsten carbide element to the structural component.
Tungsten Carbide (WC) is a tough, highdensity ceramic often used in severe service applications. Tungsten carbides are commonly known for use in highquality tooling inserts. Due to its hightemperature tolerance, stiffness, hardness, and flexural strength allow tungsten carbide is also used in other harsh applications like mechanical seals and downhole drilling components.
Sintering temperature is typically .7 to .9 of the powder's melting point. Sintering time is dependent on manufacturing process factors and material. Tungsten, for example, is sintered for a relatively long time. Standard industrial powder sintering times for different processes and materials vary from 8 .
Introducing Kinton Carbide Sintered tungsten carbide's most impressive property is the ability to resist abrasion. It is the hardest metal known to exist. Abrasion resistance can be up to 20 times greater than steel. Most of Kinton Carbide's fabrication involves brazing sintered tungsten carbide platelets to carbon steel back plates. Our brazing process results in...
Apr 08, 2010· Cobalt–Tungsten Carbide: Powders and Hard Metals Criteria for Listing Agents, Substances or Mixtures in the Report on Carcinogens . Department of Health and Human Services . National Toxicology Program . The criteria for listing an agent, substance, mixture, or exposure circumstance in the RoC are as follows: Known To Be Human Carcinogen:
Under these conditions the tungsten and copper were "mixed together" at an almost atomic level, which imparted a high degree of homogeneity and dispersion to the WCu charges after reduction. In compacts from such a charge a disperse structure with a copper matrix readily forms in the initial stage of sintering, and it is this structure ...
Wear resistant thermal spray coatings of tungsten carbide are used for their hardness and wear resistance. When choosing a tungsten carbide powder, the particle size and type of carbide selected are important in determining the correct material to combat various forms of erosion, abrasion and wear. Whereas the amount of metal matrix in the coating (nickel, cobalt, or alloy) will depend on the .
Sintering is a heat treatment process in which a large quantity of loose aggregate material is subjected to a sufficiently high temperature and pressure to cause the loose material to become a compact solid piece. The amount of heat and pressure administered during the sintering process is slightly less than the material's melting point.
A sintered metal alloy consisting essentially of tungsten'and an amount of boron of less than about percent, said alloy having a lower transition temperature, a higher recrystallization temperature, greater high temperature strength and finer grain structure than tungsten per se.
Tungsten has the highest melting point of all the refractory metals, a low coefficient of thermal expansion and a relatively high density. Tungsten's good electrical conductivity and excellent thermal conductivity are further valuable properties. The values of all these properties are higher for tungsten than they are in the case of molybdenum.
