Tungsten Carbide

Wolfraamcarbide of Widia is een keramische stof, die ontstaat uit wolfraam en koolstof en is een mengkristal. Dit relatief goedkope materiaal staat bekend om zijn grote hardheid, en wordt dan ook gebruikt in snijapparatuur. De koolstofatomen gaan in de openingen van het wolfraamrooster zitten. Het wordt gemaakt door wolfraamoxide en koolstof met behulp van waterstof te reduceren. Het werd voor het eerst in 1914 gemaakt. In 1926 werd door de Duitse firma Krupp (tegenwoordig Ken…

Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600° C (4,700° F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400°–1,600° C (2,550°–2,900° F). For fabrication, a process developed in the 1920s is employed: the powdered tungsten carbide is mixed with another ...

10-08-2020· Tungsten Carbide is the result of combining or alloying carbon with Tungsten, hard and dense metal with a high melting point. Tungsten Carbide occasions a deep gray color in …

Tungsten carbide nanorods, with diameters between 2 and 40 nm and a length to diameter ratio of 10 to 1000, can be produced by a chemical vapor transport process carried out in a continuous flow reactor, using a support metal catalyst – a carrier tungsten carbide coated with a metal catalyst (Co/P) – a volatile species source (tungsten oxide), and a carbon source (carbon black).

Wolfraam/Tungsten is voornamelijk van het element wolfraam maar ook van ijzer en mangaan (FeMn) WO4) en scheeliet (ook wolfraam, CaWO4). De grootste grondstoffen voorraden van wolfraam/tungsten bevinden zich in China, meer deposito's van wolfraam/tungsten zijn te vinden in landen als Australië, Korea, Bolivia, Maleisië enz.

Specialized in tungsten carbide round bars, with an outstanding product line of coolant and solid carbide rod, we manufacture and stock unground and ground carbide rods for you. Our h6 polished chamfered cutting tool blanks are the most popular.

Cemented carbide and cemented carbide components are made from extremely hard tungsten carbide and ductile cobalt. The two substances are mixed in the form of powder. The amount of cobalt used and the grain size of the tungsten carbide both have an impact on the performance characteristics of the carbide, such as hardness, bending strength and fracture toughness.

Waste tungsten carbide can generally be reused by APT (ammonium paratungstate) process, zinc recovery process or by pulverization. These “recycled” tungsten carbide powders generally have better, predictable densification because their surface area is smaller than tungsten carbide powder made directly from the tungsten carburizing process.

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 a factor of 10 lower.

Tungsten carbide is extremely scratch resistant at Mohs 8 to 9, and is the hardest metal for use in jewelry. Tungsten carbide rings are highly durable and are known as the ‘forever polished rings’ because they don’t easily acquire scratches or lose their luster. Tungsten carbide rings, however, cannot be resized and must be changed if the ...

Tungsten Carbide (WC) is a tough, high-density ceramic often used in severe service applications. Tungsten carbides are commonly known for use in high-quality tooling inserts. Due to its high-temperature tolerance, stiffness, hardness, and flexural strength allow tungsten carbide is also used in other harsh applications like mechanical seals and downhole drilling components.

tungsten carbide: one of the hardest known materials, used as an abrasive and in the manufacture of dental cutting instruments.

Tungsten Carbide: Is an inorganic compound (WC),that is made up if equal parts tungsten and carbon atoms. Because of this, it is not "technically" a metal. Scientifically, the tungsten and carbon that comprise it make it a compound. Tungsten carbide is also very rarely used in its plain ceramic form.

Tungsten’s hardness is what makes it so resistant to scratching. That same level of hardness also means that it won’t bend, but it will break or crack if enough force is applied to it, kind of like a diamond. "You want a pure tungsten carbide ring." Pure tungsten carbide rings are not possible. Tungsten carbide by itself is a powder.
