Tungsten or “heavy stone” (as translated literally) is gray shining metal usually found in nature in the mixture form with various other metals. Two most important minerals carrying tungsten and widely used in various industries are wolframite and scheelite. Tungsten possesses some impressive properties that make this essential metal ingredient in many industry fields.
It is highly resistant to the corrosive effect of acids and bases, has the highest melting temperature point compared to other metals; it’s flexible but firm and stable, it has a high level of hardness and brittleness, it is widely available in nature and a ingredient for processing and modifying. All of this makes tungsten perfect metal for various uses in electrical, construction, chemical and many more industries. It is widely used, in the raw state or the form of alloys with other metals. Here are just some of the most common uses of tungsten seen in the dominant industry fields.
Let there be light
Lamp industry utilizes tungsten widely. As mentioned before, tungsten has the highest melting temperature and one of the lowest vapor pressures. Both characteristics are used in lamp industry for light bulb filaments. These properties of tungsten provide high levels of luminosity, duration, and stability of generated light.
You will find tungsten filaments in common domestic bulbs, projectors, camera lights, vehicle, and airport lights, as well as in various highly specific equipment, such as medical and optic systems.
Lab utilization of tungsten
Tungsten is frequently used as a specific reagent in various biochemical analyzes and laboratory procedures. All the laboratory analyzes of minerals use tungsten to distinguish minerals according to their specific density. Also, accelerators that detect carbon in metals use purified tungsten for this process. All these procedures use purified and raw tungsten or its sodium metal tungsten form.
Tungsten alloys boost its qualities
Tungsten Metal is often mixed with other metal, and these alloys exhibit some highly useful properties applicable in many industries. One of the most frequently used alloys is the mixture of tungsten and cobalt and chromium, so called stellite, that are utilized for constructing various systems requiring wear-resistant materials.
There are, also, so-called superalloys, created by mixing tungsten with iron, cobalt, nickel or tantalum and used in some highly specific industry tasks. You can find superalloys in marine vehicles, airplanes, turbines and other systems requiring high temperature and corrosion resistance and other properties these alloys exhibit.
Tungsten is commonly added to steel to improve its characteristics. Hardness and duration of various steel tools, constructions, systems, and objects are the main desired aim when increasing the strength of steel with tungsten. It is widely used in construction industry and for manufacturing various sharp elements, knives, needles, highly precise systems and tools.
Other uses of tungsten
There are many common everyday objects you use on a daily basis that contains tungsten or its alloys. Aside from domestic bulbs and other forms of lamps, you’ll find tungsten in television sets, welding electrodes, magnets, microwave ovens, different electronic applications, vehicle parts and many other instruments.
