What Is Tungsten Carbide? Dymet Alloys

Tungsten carbide is a compound of tungsten and carbon, renowned in industry for its superior durability and high melting point (2,870 C). It is widely used in applications that require superior wear or impact resistance, such as abrasives, cutters, dies and punches. By itself, tungsten is a dense light grey metal with a melting point of 3,422 C and very high resistance to corrosion. Its ...

Tungsten Carbide Properties

8. Electrical Conductivity - Tungsten carbide is in the same range as tool steel and carbon steel. 9. Specific Heat - Tungsten carbide ranges from about 50% to 70% as high as carbon steel. 10. Weight - The specific gravity of tungsten carbide is from 1-1/2 to 2 times that of carbon steel. 11. Hot Hardness - With temperature increase to 1400°F ...

10/08/2018  Tungsten carbide is the most widely used type of high-speed machining (HSM) tool material produced by powder metallurgy, consisting of hard carbide (usually tungsten carbide WC) particles and a softer metal bond. composition. At present, there are hundreds of WC-based tungsten carbides with different compositions, most of which use cobalt (Co) as a binder. Nickel (Ni) and

Tungsten Carbide - an overview ScienceDirect Topics

Tungsten carbide powder is the base for the production of cemented carbides, the vast class of hard, wear resistant, refractory materials in which the hard carbide particles are bound together, or cemented, by a soft and ductile metal binder. Conventional manufacturing of tungsten carbide powders accounts world-wide for the bulk of the tungsten carbide powder produced. This technique permits ...

Most of the Tungsten Carbide that we machine is ...

Tungsten Carbide Design Considerations by Federal Carbide

The transverse rupture test is employed for measuring the resistance to normal stress for specific tungsten carbide grades. For design, it is advisable to consider the stresses to which a component will be subjected. Application of known stress reducing factors such as large fillet radii at corners and generous cross sections around holes will naturally lead to enhanced load resistance. Impact ...

Talking About Corrosion Resistance of Tungsten Carbide ...

Although tungsten carbide is of better corrosion resistance compared with other steel alloys in general, there are still things we need to pay attention to when choosing the correct corrosion-resistant strength tungsten carbide. Cobalt is the most widely added binder or ‘cement’ in cemented tungsten carbides due to its function to wet tungsten carbide grains on the process of liquid phase ...

For instance, tungsten carbide is commonly used for the fabrication of cutting tools for steel and tool steel. The mining industry also ...

Tungsten Carbide with Cobalt Binder SECTION 1: CHEMICAL ...

Tungsten Carbide Products in their solid form also do not present a fire hazard. Dusts, however, may present a fire or explosion hazard under rare, favouring conditions of quantity, dispersion, and particle size combined with a strong ignition source. This is not expected to be a problem under normal conditions. SECTION 4: FIRST AID MEASURES

The Difference in Tungsten Carbide and Cobalt Rings

28/09/2017  Tungsten carbide in its normal form is nothing more than a powder. Both tungsten powder and carbide powder have to be brought together and forged at very high temperatures to create the necessary bond that will result in a tungsten carbide ring. This process can be difficult and expensive, but it yields a high-quality product that will last for a long time. Cobalt. Aeya/iStock/Getty
