Description of Tungsten Carbide Powder

ungsten powders have been developed and produced to offer the purity and uniform particle size distribution demanded by manufacturers of high performance tungsten and tungsten carbide products.  Chinatungsten Online manufactures tungsten powders ranging in size from 0.40 microns (type M10) to greater than 17.50 microns (type M70).  If a standard size does not meet your specification, CTOMS can work with customers to engineer tungsten powders to meet specific application needs.  From our internally produced tungsten powders, CTOMS manufactures tungsten carbide powders ranging from nano to ultra course.  Our micrograin tungsten carbide powders are used for circuit board drills, nozzles and end mills.  Fine WC powders are used in cutting tools and inserts.  Medium and ultra-coarse powders are are required for mining tools, energy drilling tools, wear and die parts, and road construction bits.  The physical and chemical properties of CTOMS tungsten carbide powders are carefully controlled to ensure consistency in lot-to-lot performance. Our manufacturing capabilities in North America and Europe deliver word-class quality and service.
1) Tungsten carbide is a made up of chemically bonded tungsten and carbide. Its superior hardness enables it to replace steel and other metal alloys in a variety of applications.
2) Colloquially, tungsten carbide is often simply called carbide. In its most basic form, it is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, tools, abrasives, as well as jewelry.
3) Tungsten carbide is approximately four times stiffer than steel, with a Young's modulus of approximately 550 GPa,and is much denser than steel or titanium. It is comparable with corundum (a-Al2O3) in hardness and can only be polished and finished with diamond wheels and compounds.
