Tungsten carbide (chemical formula: WC) is a chemical 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, armor-piercing rounds, other tools and instruments
These tools were once only used offshore but are now used in many onshore shale formations. CoorsTek tungsten carbide-metal stator sub-assemblies are made to our customer’s design using a heat shrink technology to join the metal and tungsten carbide insert. Then we employ precision grinding to bring the size and features into exact specification.

The mechanical wear combined with the thermal effect damages the cutter’s edge. As wear progresses through the synthetic-diamond table into the tungsten carbide substrate, shearing efficiency is reduced dramatically, lowering the rate of penetration (ROP). A driller’s typical reaction to the reduction in ROP is to increase drilling
The maintenance free STR 701 offers total reliability and is the result of over 15 years constant development and improvement. An exclusive range of cleaning and grinding heads have been developed to solve the many problems faced on site.

such as tungsten carbide (WC) and silicon carbide (SiC) are ideal. In applications involving high pressures and/or large diameters, two faces fabricated from WC and/or SiC are sometimes applied to minimize the face deformations caused by the pressure forces. Although these two super-hard faces can handle quite a bit of load, it is important to

Tungsten (W) is a metal with a wide range of uses, the largest of which is as tungsten carbide in cemented carbides. Cemented carbides (also called hardmetals) are wear-resistant materials used by the metalworking, mining, and construction industries. Tungsten metal wires, electrodes, and/or contacts are used in lighting, electronic, electrical, heating, and welding

Cemented carbides are the hardest man-made metal-matrix composites. They are used in every major industry worldwide, from ballpoint pens to mining to petroleum drilling.
Jul 11, 2016· The biggest obstacle is that tungsten carbide is more brittle than steel. Experimental knives that have used a tungsten carbide compensate by either sandwiching it between stronger materials, or depositing just a thin layer directly onto the cutting edge. Not so with Sandrin’s blades, which are solid pieces of tungsten carbide.
Tungsten Carbide vs. Titanium. Although Tungsten was originally used for light bulbs in the early 1900’s we know today that Tungsten is a highly versatile and necessary metal for many industrial tasks.
