The Importance Of Tungsten In Today’s Industry

Tungsten is one of the most important materials in the modern metal industry, but many other industrial sectors are directly connected with the use of Element 74. In other words, tungsten alloys have taken over the world, and they are nowadays immensely important elements in the overall system of our global industry. Learning a thing or two about this metal will, therefore, offer you a chance to get acquainted with this highly valuable commodity, and that is why you should stick with this in-depth guide. In some upcoming articles, we will thoroughly discuss Tungsten Heavy Alloy since many people have interest in various tungsten uses.

General Overview

As we already mentioned, tungsten stands at the position number 74 in the periodic table, and many people refer to this element as Wolfram. However, these two names mean the same thing, i.e. they relate to a highly durable metal which provides interesting and unique characteristics and features. The actual term tungsten originates from the Swedish words “tung sten” which translate to “heavy stone”, and this convenient use of words perfectly illustrates the nature of the material in question. As a matter of fact, it is a widely accepted fact that tungsten is one of the toughest substances on the face of the Earth, and only diamonds can cut through sheets of tungsten, but only with the use of highly sophisticated methods and techniques.

The Characteristics Of Tungsten Alloys

Element 74 is also the metal which has the highest melting point of all other metals which we know off, and it starts to melt only at temperatures higher than 3.422 degrees Celsius. The extremely high melting point is a valuable asset which allows tungsten to find its purpose in many branches of industrial production. However, this is not nearly the only characteristic of this metal that attracts attention, and high density and excellent hardness are also among intriguing and interesting features. Tungsten is two times heavier than lead, and with its high density, it is possible to create items of small volume but of incredible weight out of this material.

Tungsten is frequently used in a form of alloy, and depending on the actual amount of the metal – these alloys can serve different functions in the modern industrial process. Alloys can have amazing tensile strength, they can be easy to machine, and they can provide excellent wearing resistance. Furthermore, they can be resistant to corrosion as well, and on top of all that – tungsten alloys which are used in the modern-day industry are Eco-friendly and non-toxic.

How We Use Tungsten Alloys Today

Since tungsten alloys can offer so many positive characteristics, it is perfectly natural that humans are looking for ways to exploit all those benefits. For instance, we nowadays use tungsten alloys to create bullets and other projectiles in the military. On the other hand, tungsten can also serve as a protective element in shields which are used around x-ray machines. Aerospace and automotive industries are also relying on tungsten alloys, just the same as sports and leisure sectors often use tungsten to create various types of equipment, such as golf clubs, darts, and so on.

The many uses of Tungsten

In the past, people have always aimed to use precious metals to produce stronger and better materials. One of the rare materials named Tungsten is particularly used in many industries for its highly valued properties. The reason why Tungsten is so valued is that it possesses a high resistance to heat, corrosion and it’s extremely durable under duress.

The metal, also known as wolfram, has the density of 19.35 g/cm³, with its melting point is 3410.0 ℃ or 3683.15 K, 6170.0 °F, and boiling point is at 5660.0 ℃ or 5933.15 K, 10220.0 °F. For these reasons, this rare metal has found its way into many appliances and industries as the main component or an alloy to various products. Tungsten Heavy Alloy is an excellent choice for vibration damping, centrifugal compensations, making inertia sensors etc.

– Alloys

Even though Tungsten can’t be found in its pure form in nature. A lot of times it is used as a pure metal, but only after extraction, or it can be combined with many other metals to form alloys. Since Tungsten alloys are strong, resistant to corrosion and wear, are flexible and transfer electricity when needed.  For example, tungsten-steel combination alloys are the materials that are used in the production of rocket engines. Its high heat resistant property makes it one of the best materials to use it in such products. There are also super-alloys that contain Tungsten.

They are used in the production of turbines, coatings and many different products that need to be wear-resistant. The best quality darts use Tungsten and nickel alloys.

– Electrical & Electronics industries

The single biggest use of Tungsten today is in the production of the common light bulbs. Its high melting point combined with low vapor pressure make it perfect for the light bulb filament. Tungsten is also used as filaments  in cathode tubes and vacuum tubes.

Since Tungsten also has amazing conductive properties, it’s also used in electrodes, for example in an electron microscope. Tungsten’s high tolerance for heat also makes it a perfect metal or alloy in electronic appliances. A good example is an integrated circuit and for X-ray machines.

– Other applications

Besides the applications of the Tungsten metal that are mentioned before, tungsten has even more. Tungsten’s thermal expanding capabilities are similar to borosilicate glass and for that reason, it can be shapedinto making glass-metal seals. Tungsten can also see a high use in the modern design of jewelry. It can substitute platinum and gold due to its similar metal density as gold.

Additionally, in the near future, we could see Tungsten in energy saving technology as its oxide has two special properties (polycondensation and intercalation).

All in all, Tungsten is one of the best rare metals to use to make reliable products that will have a longer lifespan and will be stronger if imbued with Tungsten. The metal will continue to impress and find new uses in future technology because it is very hard to ignore the fact that the metal alone provides the highest resistance to heat when it comes to metals.

The Properties, Applications, and Alloys of Tungsten

Since ancient times, people have been mining the earth for precious metals, with the desire to use them to create the best version of tools and weapons that they could. During one such mining expeditions, a rare metal called Tungsten was mined. Tungsten, also known as Wolfram is a silver-gray-white metal that is one of the metals which is highly resistant to heat. Tungsten is also a lot more resistant to fractures than any diamond is and is twice, if not more, harder than your regular steel.

As such, Tungsten has found its use in lots of industries as the main component or an alloy. Its ability to resist high temperatures, acids, and its durability have made this metal a highly desirable addition in almost any industry in our modern times.

– Specifications

Tungsten is a very durable metal with its Moh’s Hardness at 7.5, it’s density coming off at 19.24g/cm3, its Melting Point being 6192°F or 3422°C and Boiling Point at 10031°F or 5555°C, Tungsten is one of the most used metals when it comes to protection from heat and radiation.

Additionally, what should be noted is that Tungsten is rarely found as a lone metal, it’s mainly extracted from Scheelite and wolframite, but tungsten can also be recycled which amounts to about 30 % of the total global Tungsten supply. The lead producer in Tungsten is China which produces and exports about 80 % of the total world Tungsten supply.

– Applications:

Like we mentioned before, people have been mining to find metals that will help them upgrade their existing tools and weapons. Tungsten has found its primary use in one of the tools that were used by everyone on the planet. Namely as a filament  in the light bulb industry.

With Tungsten’s strong durability and high resistance to heat, Tungsten has been used as a wire filament that is placed in the middle of light bulbs that power billions of homes all around the planet. The aptitude to keep its shape at extremely high temperatures has helped Tungsten filaments cement their role as the main light bulb component.  For example, Tungsten Heavy Alloy is the no.1 material for anti-radiation shieldings.

Tungsten filaments are also used in many other household applications, such as: heating elements, microwave ovens, cathode tubes in computers, tv, electrical furnaces, many wall wires etc.

The metal can also be present in furnaces, construction tools and welding equipment. Its density also helps the metal to be used in fishing sinkers, darts, counterweights, and similar products.

Alloys of Tungsten

If you want to increase the corrosion resistance, heat resistance and water resistance of any metal, than Tungsten is the metal you want to combine it with. Many tools that are used for precise cutting have Tungsten.  If combining Tungsten with steel you get an alloy that is perfect in the production of nozzles for a rocket engine, since any alloy with Tungsten is going to have high heat resistance. Other alloys of Tungsten are Stelite (a combination between tungsten, chromium and cobalt), which is used when making pistons and bearing due to its strong durability and extremely high resistance to wear and water resistance.

What Are the Uses of Tungsten?

Tungsten, as we all know, is a rare metal that derives its name from “Tung Sten” in Swedish, wich is roughly translated to “Heavy stone”. The natural color of Tungsten is grayish-white but it rarely is found as a lone element. The metal is pretty stable and is very durable when it comes to it being exposed to acids and other bases. The metal itself has one of the highest melting points of all metals on the periodic table. With this perk alone, Tungsten is one of the most valuable metals that can be processed by man. Its functionality can be present in many valuable applications that can include electrical uses, manufacturing uses, construction, chemical, and of course a protective use as it’s a metal that can protect from radiation. Tungsten Heavy Alloy is often used in XRay examinations where the protection from radiation is essential.

But, you are probably wondering where can you exactly use Tungsten in your daily life, or where is it actually present. Well, we will list some examples of where the rare metal Tungsten can be present in our daily lives, and some not so common as well.

– Filament for light bulbs

One of the most well-known uses for Tungsten is its presence in the standard light bulb that everyone uses in their home. So, it’s safe to say that the largest commercial use of Tungsten is in its application in the lamp industry. Since Tungsten is capable of withstanding incredible high temperatures and has virtually none vapor pressure, Tungsten is the perfect metal for a light bulb. Especially light baulbs which won’t be turned off for several hours where they will emit lots of heat and be subjected to incredible electric voltage. Tungsten can be seen in all kinds of filaments, of which some of them are: reflector lamps, projectors, domestic lamps, vehicle lights, street light lamps, camera lights and much more light bulb products.

– Alloys

Tungsten has a particular quality when it comes to rare metals. Namely, Tungsten has the property of making other metals stronger when they are combined with it. When you mix Tungsten with other metals, an alloy is created with special properties, which can be used in a variety of applications in almost any industry known to man.

Tungsten can be mixed with several other metals to create a high water-resistant alloy, for instance, if you mix cobalt and chromium with tungsten you will get stelites, which is a metal that is highly water resistant. Stelites can be used to create pistons, valve seats, ship building materials, and similar products. When you mix Tungsten, irmolybdenum, rhenium, tantalum with iron or cobalt you get superalloys. Superalloys have special properties that can result in very high resistances when it comes to heat tolerance, corrosion resistance, and extreme durability. Superalloys such as these can be found in use with all kinds of marine vehicles, aircraft engines, turbine blades different power supplies and much more.

– Steel and Tungsten

When you add Tungsten to steel it will increase the strength of steel tenfold. To be specific, Tunsgen increases the cutting capacity and hardness of the steel. Basically, all the tools used in construction and similar industries are mad from steel and tungsten. On the plus side tungsten also makes most of those tools highly resistant to heat and acid.

– Tungsten in laboratory use

When it comes to laboratories Tungsten is also highly present in that field. For instance, a biochemical analysis Tungsten is a reagent in the form of Sodium Tungstate. As Sodium Metatungstate, it is used as a luquidseperation tool to seperate minerals on the basis of their density.
