Tungsten has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C has the highest tensile strength. It has excellent corrosion resistance and is attacked only slightly by most mineral acids. More Information on Tungsten (Atomic Structure, Electron Configuration, ...

WES Engineering Solutions are a UK based Engineering Solutions company; services we provide include Advanced Engineering, Hardmetal Engineering, Resistance Welding, and Design Consultation.

Oct 07, 2014 · Tungsten carbide (WC) is well known as the ingredient of cemented carbides based on WC-Co because of its exceptional hardness, excellent wear resistance, a high modulus of elasticity and retention of its room temperature hardness at elevated temperatures. Due to the unique combination of strength and toughness, cemented carbides are universally ...

A general purpose grade combining good wear resistance and moderate toughness. FC4 is appropriate for use in a wide variety of wear applications where impact or shock are not important factors.

Kermetico HVAF and HVOF tungsten carbide coatings have excellent resistance to sliding wear, abrasion and erosion despite lower corrosion resistance than WCCoCr. The Kermetico HVAF WCCo coatings are gas-tight (non-permeable to gas and liquid) at 50 microns | 2 mils.

Tungsten Carbide Blades. With optimum grade selection, submicron grain size tungsten carbide can be sharpened to a razor edge without the inherent brittleness frequently associated with conventional carbide. Although not as shock-resistant as steel, carbide is extremely wear-resistant, with hardness equivalent to Rc 75-80.

"Tungsten carbide, not to be confounded with tungsten alloy, which is metal, is the ceramic of choice when it comes to wear and abrasion resistance. Cutting tools for steel and tool steel are ...

Tungsten's desirable properties such as resistance to high temperatures, its hardness and density, and its strengthening of alloys made it an important raw material for the arms industry, both as a constituent of weapons and equipment and employed in production itself, e.g., in tungsten carbide cutting tools for machining steel. Now tungsten is ...

Aug 02, 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 .

Jul 04, 2011 · Tungsten Carbide We use Tungsten Carbide every day in a variety of products, for use in a number of different applications throughout many industries. It is an incredibly versatile and useful material due to its unique properties. There are many different applications within the Oil and Gas Industry from exploration to drilling and pumping where hard and exotic materials are commonly used.

Crack-resistance - Titanium is much more crack-resistant than naturally brittle tungsten carbide. Tungsten carbide's extreme hardness paired with its brittleness means that tungsten carbide rings can crack or shatter if struck against a hard enough surface. While some higher grade tungsten carbide bands demonstrate decreased brittleness, as a general rule titanium rings are still a better fit for men who .

Tungsten Carbide: High flow with abrasion resistance. The high thermal performance of the tungsten carbide keeps the nozzle tip hot, thus allowing faster printing speed without sacing the quality. Tungsten carbide has exceptional wear resistance due to its high hardness. Both the nozzle hole size and height will always stay the same, no matter how long or how hard you use it.

Tungsten Carbide Rings – Why Are They Better? Tungsten carbide rings in many aspects, primarily in the areas of strength, class and style. Tungsten as a substance is extremely hard, ten times harder than gold, and this property leads to a wonderful strength when fashioned into a ring. Tungsten rings will not bend out of shape or distort with ...

Work history at the time of presentation revealed that for 20 yrs he had been a grinder of /tungsten carbide/ tools. There were no other important present or past exposures. Chest radiography revealed multiple irregular & rounded small opacities throughout the lungs, with contraction of the upper lobes. There were no pleural or cardiac ...

Nanostructured Tungsten Carbide Coatings Protect Against Corrosion . Extensive testing of chemical vapor deposition (CVD) tungsten carbide coatings has proven that low-temperature CVD coatings can provide a viable corrosion solution. ... and have limited abrasive/erosive resistance and .

• Overview

There are over a dozen different grades of Tungsten Carbide. When evaluating equivalents of Tungsten Carbide grades the important criteria is to specify two of three factors; binder content, hardness or grain size. Balance must be made between wear resistance and impact resistance.
