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 ...
The 10xx series is the most popular choice for carbon steel used in knives as well as katanas. They can take and keep a very sharp edge. [59] 1095, a popular high-carbon steel for knives; it is harder but more brittle than lower-carbon steels such as 1055, 1060, 1070, and 1080.
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]
Can be used up to 900 °C. There are many sort of cemented carbides like ones made of tungsten carbide and cobalt or cermets. Cutting ceramic: They are even harder than cemented carbides but have lower toughness. Aluminium oxide and silicon nitride are used. The latter has higher toughness, but can't be used for machining steel, due to very ...
Some of them, including titanium carbide and tungsten carbide, are important industrially and are used to coat metals in cutting tools. [3] The long-held view is that the carbon atoms fit into octahedral interstices in a close-packed metal lattice when the metal atom radius is greater than approximately 135 pm: [2]
Tungsten steel is any steel that has tungsten as its alloying element with characteristics derived mostly from the presence of this element (as opposed to any other element in the alloy). Common alloys have between 2% and 18% tungsten by weight along with small amounts of molybdenum and vanadium which together create an alloy with exceptional ...
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, [54] [55] both as a constituent of weapons and equipment and employed in production itself, e.g., in tungsten carbide cutting tools for machining steel. Now ...
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.
