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 sintering [7] for use in industrial machinery, engineering facilities, [8] molding blocks, [9] cutting tools, chisels, abrasives, armor ...
Used by Hattori knives in their kitchen knives KD series. ZDP-189 is produced by Hitachi steel using the PM process. It contains 3% carbon and 20% chromium and contains tungsten and molybdenum. Used by several custom knife makers and factory makers including Spyderco and Kershaw in the limited run of the Ken Onion Shallot folders. The Henckels ...
A scoring knife or scoring tool is a handheld tool used to cut a groove in a sheet of material. The cutting edge of the knife is often made of hard material such tungsten carbide. The scoring knife is drawn across the material in a straight line (with the help of a straightedge), creating a scratch or score in the sheet. The material can then ...
[8] [9]) Alternatively, tungsten carbide blades can be used in knife sharpening. A clamp-on knife sharpener. The rod guides the sharpening stone to maintain a consistent angle. The angle can be adjusted by moving the guide posts up or down. This sharpener uses a diamond dust coated stone to remove metal from the knife blade.
Tungsten compounds are often used as industrial catalysts. Its largest use is in tungsten carbide, a wear-resistant metal used in metalworking, mining, and construction. [22] About 50% of tungsten is used in tungsten carbide, with the remaining major use being alloys and steels: less than 10% is used other compounds. [23]
The first cemented carbide developed was tungsten carbide (introduced in 1927) which uses tungsten carbide particles held together by a cobalt metal binder. Since then, other cemented carbides have been developed, such as titanium carbide, which is better suited for cutting steel, and tantalum carbide, which is tougher than tungsten carbide. [1]
A hand-held tungsten carbide knife sharpener, with a finger guard, can be used for sharpening plain and serrated edges on pocket knives and multi-tools. Tools and materials [ edit ]
A glass cutter may use a diamond to create the split, but more commonly a small cutting wheel made of hardened steel or tungsten carbide 4–6 mm in diameter with a V-shaped profile called a "hone angle" is used. The greater the hone angle of the wheel, the sharper the angle of the V and the thicker the piece of glass it is designed to cut.
