It is quite certain now that Tungsten Metal proved its worth in the metal industry. It reached mainstream usage and it turned out that it is good for so many different things. Its quality is supreme and it is the best when it serves as a supporting element like in alloys because it literally enriches the alloy with all its benefits. This outstanding quality material became quite popular in the metal industries because of this and it turned out that it provides many great advantages. Tungsten alloy has some extraordinary properties and it can perform much better than any other compound.
Different industries use different alloys and this means that not all alloys require all of the benefits that tungsten offers. With this in mind, worldwide industries made dozens of different tungsten alloys in a different form and quantity in order to better exploit the numerous uses that this outstanding metal element has.
Tungsten is mostly used for manufacturing of heavy machinery but it can also be used for tools that are used with heavy duty. Tungsten alloys have enough strength alone that they can support such manufacture of machinery and tools and it turned out that tungsten tools and machinery last longer than machines and tools made of other metals.
This is simply due to its benefits that make it much better than other elements. One of the most fascinating characteristics of tungsten is how incredibly resilient it is. Its resistance to wear is simply astonishing. Its ability to withstand high speed oscillations is what makes it perfect for alloys. It is also extremely resilient to heat as well. This is particularly important property and it has the highest melting point and that makes it perfect for alloys. Industries thrive on it.
Tungsten Metal was discovered in the 17th century, and many people compare its hardness to diamond. This metal has a great heat resistance, and this is one of the reasons why it is so broadly used. It has found many useful applications, and one of the most important ones is in the medical industry. Tungsten alloys are slowly changing the way on how we look at the world, but at the same time protecting our well – being. The fact that Tungsten is a non – toxic metal makes it ideal for hospitals and medical facilities. It won’t endanger the patients’ health, and it will keep them protected from harmful gamma rays, which are number one cause of cancer.
Tungsten alloys in diagnostics
They are often used as components or final parts for many diagnostics and therapeutic medical devices, for example, multileaf collimators, which are used in radiology. High-density alloys are used for these devices.
For instance, this particular device directs radiotherapy so precisely and treats affected area, but delivering the appropriate doses to patients. In tears of preciseness, multileaf collimator plays an important role, because every patient’s needs to receive an adequate therapy with the precise doses, but at the same time, it protects the patient’s body.
Considering the density and strength of tungsten alloys, they are the first choice used for radiation shielding. This metal has a high potential to absorb the particles and block the X – rays and gamma rays. This is one of the reasons why many x – ray tubes and x – ray technology is based on tungsten alloys.
Apart from this, tungsten alloys are used for much medical equipment, for example, syringes.
Considering that patients suffer from severe diseases, like cancers and tumors, sometimes doctors need to inject the radioactive substances into their body to prevent the spreading. In this case, they use equipment made of Tungsten alloys, which will help them protect their surroundings from radiation.
The features of Tungsten
To understand its importance, we first need to explain what Tungsten stands for. This is probably one of the hardest metals on the planets, it has the highest melting point, and it’s not toxic, which makes it critical to many industries and businesses.
In this way, it is indispensable in medicine because it will not harm the patients and protects them from radiation. But not only medicine has the use for Tungsten, but also auto and aero industry, as well as heavy industry, use Tungsten in their production.
Considering that lead has been almost banned from the use, Tungsten has proudly taken its place. We all know that in the past lead was widely used in medical facilities, but it has proven to be toxic for patients. On the other hand, Tungsten is one of the rare metals which is toxic – free, safe to use and it doesn’t evaporate. As the technology advances, we can expect many great things to unfold as well as the further progress of this metals and its use.
Tungsten name originates from a Swedish word “Tung Sten” which means “heavy stone.” When it’s found in nature, this metal has a silvery – gray color, and it is resistant to acid, bases, and heat. Scientists around the world compare tungsten to diamond because of its hardness. This metal is very durable, which indicates it can uphold a lot of pressure. Tungsten is present in many industries, especially in heavy industry. Tungsten has the highest melting point among all metals; this is one of the reasons why it’s in such high demand.
What are Tungsten alloys?
Tungsten can be used as a pure metal, or it can be mixed with other metals to produce Tungsten alloys. They have unique features, and they have managed to find various uses in many industries. When Tungsten is mixed with cobalt and chromium, we get a compound called stellites, which has high wear – resistant performance.
Stellites is used in bearings, pistons and valve seats, as well as in applications that demand materials which have high resistant properties. Tungsten is also mixed with cobalt and nickel. Tungsten alloys are also used in medical industry when x – rays or radiation are involved in protecting the patients. They have also found their application in military or aero industry.
Filament and production of light bulbs
The most famous use of tungsten is in light bulb filaments. This is one of the reasons why tungsten found such a broad application in lamp industry. This metal can tolerate high temperatures because it has the highest melting point among all metals. Tungsten has a low vapor pressure, because of this our light bulbs last that long and have increased luminosity. Tungsten Metal, or better say”tungsten alloys”, is used in domestic lamps, vehicle lights, and reflector lamps, but also for lamps which have a particular purpose. Considering the bulbs are under a lot of pressure and high heat, it shouldn’t surprise us why this metal found its use here.
Tungsten – steel alloys
When tungsten is mixed with steel, it becomes stronger. Tungsten increases hardness and cutting capacity with steel. This meal is the principal component in steels used for tools and constructions. Steel alloys mixed with tungsten are used for cutting and in producing metal parts. In addition to this, tungsten contains high-temperature resistance which makes it perfect for this.
Considering this is one of the hardest metal on earth when combined with steel, it gets excellent performances.
Innovations and new discoveries
In the future, we can expect even bigger changes in production of Tungsten alloys. It tough to find a metal in nature which is none – toxic and Tungsten is one of that. Considering that global warming is a serious issue that needs to be addressed and is affecting our whole planet, tungsten may play a significant role in the following years. This metal doesn’t release a vapor, and it is not dangerous for our environment. We are sure that Tungsten and Tungsten Alloys will become one of the most demanding metals in the future.
