Tungsten carbide is a kind of alloy made by powder metallurgical process with the refractory carbides (such as tungsten carbide, titanium carbide, tantalum carbide, niobium carbide, vanadium carbide and chromium carbide) as the hard phase and cobalt or nickel as the binder. It is divided into cutting inserts, wear parts, mining tools, profiles and hard-facing material in terms of the basically applications.
Tungsten carbide is the hardest man-made metal-matrix composites. They are used in every major industry worldwide, from ballpoint pens - to mining - to petroleum drilling. The unique properties of carbide in its carious compositions and forms have made process industries and durable goods manufacturers more efficient by reducing machine downtime. The term cemented carbides refers to metallic carbides - fine particles of tungsten carbide bonded or cemented together in a matrix of a metallic element of a lower melting point such as cobalt or nickel. The process of powder metallurgy is skillfully employed to produce cemented carbides.

The production of carbide involves a process the complexity of which is, in fact, extraordinary. The base materials, tungsten carbide and cobalt, are combined by applying an exceptionally wide variety of mixing ratios. By adding further materials, such as chromium, nickel, tantalum and titanium, special characteristics can be achieved, e.g. corrosion and heat and wear resistance.
Tungsten carbide bar is widely known as one kind of carbide cutting tools, it’s available for different grinding geometric parameters and suitable for both cutting materials and nonmetal materials, also it can be applied to conventional, carbide inserts semi-automatic lathe, automatic lathe and planning machine to work grooves and operate cutting, etc.

Tungsten carbide plates are commonly used as the material of various tool parts. High densities, hardness, meet the ISO standard.
Most of this tungsten carbide wear parts and the mining tools are made of straight WC-Co hard metals without any addition of other carbides.
Fine and ultrafine grained WC hard metals have become more and more important today in the field of wear parts, tools for chipless forming and cutting tools for cast iron, non ferrous alloys and wood.
Tungsten carbide buttons are widely applied in geological prospecting, coal mining and oil well boring. Because of its wear resistance and hardness (9.8 Moe's scale), tungsten carbide is ideally suited for wear parts, other machine parts and dies which are subject to severe service conditions, such as high temperatures, corrosion and abrasion. In recent years, tungsten carbide has emerged as a superior alternative to steel in many industrial applications.
Tungsten Carbide Burrs/Carbide Rotary Files is a new tape milling cutter with high efficiency, instead of grading wheel bur with handle. It can cut and process various kinds of metal (including hardened steel) and nonmetal (such as marble) with hardness up to HRC<65.
Tungsten Carbide blades are known as being sharp and durable. They are wear-resistant, and can be used in a variety of industrial applications where extremely sharp cutting instruments are needed. For example, carbide blades are well suited to cutting reflective materials for plotting and sign making. Although prone to chipping and breakage, when these pitfalls are avoided with the proper engineering, tungsten carbide blades can sustain significant industrial stresses.
1. The diamond powder is selected in a higher degree.
2. The claws of the interface are changed to be net-grooves-shaped which formed by 20 straight vertical grooves, and the depth of the grooves are shallower.
3. Improved the interior structure of the sintering cell that makes the pressure and temperature to be more uniform. It is very important for the PDC sintering.
4. Using new super heat-resistant metal, to avoid being contaminative during sintering.
5. The sintering processing is amended, and the bonding strength of the diamond-diamond key among the diamond layer is improved
6. Increase the content of diamond, and increase the thickness of diamond layer up to 2.0mm.
