What is tungsten carbide fact?
Tungsten is a heavy, gray metal with bluish overtones. When mixed with black carbon, tungsten carbide is created. Tungsten carbide facts are an inorganic chemical compound containing equal parts of tungsten and carbon atoms. The cobalt in tungsten carbide is the element of most concern. Tungsten carbide fact often contains nickel and chromium, which can also cause asthma. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, other tools and instruments, and jewelry.
Chemical Properties of Tungsten Carbide Fact
At high temperatures WC decomposes to tungsten and carbon and this can occur during high-temperature thermal spray, e.g., in high velocity oxygen fuel (HVOF) and high energy plasma (HEP) methods.
Oxidation of WC starts at 500–600 °C. It is resistant to acids and is only attacked by hydrofluoric acid/nitric acid (HF/HNO3) mixtures above room temperature. It reacts with fluorine gas at room temperature and chlorine above 400 °C (752 °F) and is unreactive to dry H2 up to its melting point. WC dissolves readily in diluted hydrogen peroxide.
Physical Properties of Tungsten Carbide Fact
Tungsten carbide is high melting, 2,870 °C (5,200 °F), extremely hard (~9 Mohs scale, 1700–2400 Vickers number) with low electrical resistivity (~2×10−7 Ohm•m), comparable with that of some metals. Tungsten carbide is a much more versatile material than most other metals. It is four times as hard as titanium and twice as hard as steel. Tungsten carbide is much more heat resistant than both metals as well.
Tungsten carbide fact has a variety of uses due to its unique physical properties. Its molecular formula is WC, and it is very similar in nature to titanium carbide. Since it does contain two different elements, it is classified as a chemical compound. Sometimes, tungsten carbide fact is just referred to as carbide in everyday speech.
Tungsten carbide fact is a compound made of the elements tungsten and carbon. Its density makes it highly valuable in the military, and the mining and manufacturing industries. Since its creation, tungsten carbide has even been used to make wedding bands.
Hardness of Tungsten Carbide Fact
Tungsten carbide fact measures a nine on Moh's hardness scale, meaning it is about as hard as corundum, but not as hard as diamond. In order to polish or finish an item made of tungsten carbide fac, a diamond must be used because any other metal or mineral would crack and break. Only a diamond is hard enough to be able to scratch tungsten carbide. Its density also surpasses the density of titanium.
Composition and Properties of Tungsten Carbide Fact
Tungsten carbide fact is created when tungsten and carbon are combined in equal amounts. In order to create tungsten carbide, the process has to be carried out at temperatures between 1,400 and 2,000 degrees centigrade. The resulting product, tungsten carbide, has an extremely high melting point of about 5,200 degrees Fahrenheit and a low electrical resistance, meaning it readily conducts electricity.
Military Uses of Tungsten Carbide Fact
Because tungsten carbide is so hard and dense, the military uses it to make armor-piercing ammunition. It was first used during World War II by German fighters vs. Soviet tanks.Tungsten carbide fact is also used as artillery ammunition. Smaller caliber weapons, such as machine guns and handguns, also can use tungsten carbide. The use of this ammunition leads to more destruction as few forms of armor are able to stop the bullet.
History of Tungsten Carbide Fact
Tungsten carbide fact was first used in the 1920s when a German light-bulb company sought ways to make cheaper wiring for the light bulbs. Since tungsten carbide fact has a high melting point, this compound worked perfectly for light bulbs because the temperatures inside them get very hot. The production of tungsten carbide fact was perfected by the 1930s and other elements were also added in order to make the compound useful for other applications.
Industrial Applications of Tungsten Carbide Fact
Due to the hardness of tungsten carbide, its creation was a breakthrough for the mining industry. Since it is much harder and denser than steel, tungsten carbide, when used on drills, is able to drill through more rock and have a longer lifetime than steel drills. Tungsten carbide is also used as a machine cutter to cut through steel and other metals.
