Metal prices are the prices of metal as a commodity that are traded in bulk at a predefined purity or grade. Metal can be split into three major categories, precious metals, industrial metals and other metals. Precious metals and industrial metals are priced by trading of those metals on commodities exchanges. [1]
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 ...
In chemistry, a carbide usually describes a compound composed of carbon and a metal. In metallurgy , carbiding or carburizing is the process for producing carbide coatings on a metal piece. [ 1 ]
The prices are usually quoted for tungsten concentrate or WO 3. ... Sometimes manufacturers or retailers refer to tungsten carbide as a metal, but it is a ceramic. [79]
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]
It is also used as an abrasion-resistant surface coating on metal parts, such as tool bits and watch mechanisms. [4] Titanium carbide is also used as a heat shield coating for atmospheric reentry of spacecraft. [5] 7075 aluminium alloy (AA7075) is almost as strong as steel, but weighs one third as much. Using thin AA7075 rods with TiC ...
Stainless steel is a popular class of material for knife blades because it resists corrosion and is easy to maintain. However, it is not impervious to corrosion or rust. For a steel to be considered stainless it must have a Chromium content of at least 10.5%. [24] 154CM / ATS-34 steels. These two steels are practically identical in composition ...
Cementite (or iron carbide) is a compound of iron and carbon, more precisely an intermediate transition metal carbide with the formula Fe 3 C. By weight, it is 6.67% carbon and 93.3% iron. It has an orthorhombic crystal structure. [4]
