tungsten Anlamı

• When used as an alloying element it increases the strength of steel at normal and elevated temperatures Its 'red hardness' value makes it suitable for cutting tools as it enables the tool edge to be maintained at high temperatures In conjunction with other alloying elements it finds applications in heat resisting and other severe service conditions. a heavy gray-white metallic element; the pure form is used mainly in electrical applications; it is found in several ores including wolframite and scheelite.
• Rare metallic element with extremely high melting point Used in manufacturing TIG electrodes.
• A metal commonly used to make the plugs used for connecting metal wires to one another or to the devices in integrated circuits Tungsten is usually deposited by CVD, unlike almost all the other commonly used metals in semiconductor manufacturing which are generally deposited by sputtering This makes it excellent for filling deep narrow holes such as the contact holes connecting the metal wires to each other and to the semiconductor devices in an integrated circuit back to top.
• Chemical symbol W Gray metal with high tensile strength; ductile and malleable, immune to atmospheric influences and all acids but strong alkalis Extremely pliable; can be drawn into filament for incandescent bulbs, rolled into thin sheet for radio tubes; ground into powder, and mixed with carbon and then embedded in soft metal to produce carbide tools, or alloyed within steel to make abrasion-resistant tool and die steels.
• A high melting point metal used in pure or near pure state as an electrode material.
• Tungsten is a gray-white heavy high-melting ductile hard polyvalent metallic element that resembles chromium and molybdenum in many of its properties and is used especially for electrical purposes and hardening alloys.
• This is a metal found in a number of minerals, but chiefly in wolframite In colloidal form it is used in the filaments of lamps As tungsten carbide it is used in a wide variety of cutting tools to give them long cutting life.
• tunsten. wolfram.
• Scheelite, or calcium tungstate. a heavy gray-white metallic element; the pure form is used mainly in electrical applications; it is found in several ores including wolframite and scheelite.
• Specific gravity, 18.
• Atomic weight, 183.6.
• Symbol W.
• When alloyed in small quantities with steel, it greatly increases its hardness.
• It has both acid and basic properties.
• A rare element of the chromium group found in certain minerals, as wolfram and scheelite, and isolated as a heavy steel-gray metal which is very hard and infusible.
• tungsten.
