Application of Tungsten in Military

Application of Tungsten in Military

Fun fact if you didn’t already know that Tungsten is used by the military to produce bullets. Not just any kind of bullets, with Tungsten the military is producing armor penetrating bullets and also fragmentation ones that have a devastating effect on the target because in the moment of impact it will shred the target. Tungsten metal is used in a lot of areas from bullets, grenades to even rockets. The combination of tungsten and carbon the Tungsten Carbide is also used because it has, even more, strength and it is more durable than the pure tungsten. This metal is just perfect for making penetration bullets and shrapnels.

Companies that are producing bullets for the military all around the world are started to use tungsten for the production of ammunition. The reason behind it is very simple, it has been proven that this metal is friendly to the environment. Especially when they compared it to the lead, which has very damaging power to the environment. A lot of research has shown and proven that even the combination of tungsten and carbon is clean material that has no bad effects on the environment and it is the perfect choice for the production of ammunition and other products.

Vehicle use

Military WAnother very common use of this metal is in military vehicles, usually, helicopters and aircraft but sometimes even for armored vehicles. They use tungsten in helicopters to even out the weight of the rotors, skids or the nose. They use it quite often because this metal has a great size to weight ratio. That means that a small piece is weighing a lot. Sometimes it is also used for protection of some vehicles because of its strength.

Strategic Significance for the Military

MilitaryThe key to new and modern equipment are new materials that are more destructive, stronger and environment-friendly. However, to find such a material can be very hard. Some countries are giving very high priorities to the development and maybe the discovery of new and better materials. It was very hard for them to find a material that is better that tungsten, the one candidate that was somewhat better was the Depleted Uranium that had more destructive power but it had a huge disadvantage and that was the non-environment friendly side of it.

In Kuwait, after the war, they found out that the depleted uranium that was used left a deadly dust. After that discovery, the use of the depleted uranium was significantly dropped. Nowadays because of that, the use of tungsten bullets is very high. However, it is not easy to get a hold of a lot of raw tungsten because more than 80% of the world supply is from China.

Guidelines for Tungsten Electrodes

Guidelines for Tungsten Electrodes

The first and the most important step you need to do when you want to use a TIG welder is to select 1 out of the 6 most regularly used tungsten electrodes for yourself. Furthermore, the preparation of the tip is crucial. Here is the list of those 6 types of electrodes from which you need to choose one.

  • Pure Tungsten
  • 2 % Thoriated
  • 2 % Ceriated
  • 5 % Lanthanated
  • Zirconiated
  • Rare Earth

Thorium-Tungsten ElectrodeThis metal element is quite rare, and it is used for making electrodes for gas tungsten arc welding. This welding process mostly relies on the hardness and the strength of the tungsten. It needs to be resistant to extremely high temperatures in order to carry current all the way to the arc. The melting point of this metal is the thing that makes it so great for manufacturing electrodes for TIG welding. The Tungsten metal is the metal that as the highest melting point of any other metal.

You can find these electrodes in various sizes (length). They are made out of either raw tungsten or they are mixed with some other elements. When you are choosing the type of the electrode that you will use, you need to look out for many different things such as the type of the material that you want to weld, the thickness of that material and the type of the current (AC or DC). If you don’t choose the right one for the job, you might have to do it all over again or you can even risk the contamination of the environment. Every type of the tungsten electrode is marked by a different color, to avoid any confusion of the type. You can see the color on the tip of the actual electrode.

Pure Tungsten

If you want to find an electrode that is made out of pure Tungsten, then you need to look for a green tip on the electrode that will indicate that it is made out of pure Tungsten. This type has the highest consumption rate.


The tip of this type of electrodes is colored red. Nowadays most people use this type of electrodes because they are last longer and they are very simple to use.


These electrodes are colored orange. This type has shown that it will perform best in DC welding under low current. However, it can be also used with AC. These electrodes are used for welding delicate pieces.


The Lanthanated electrodes have their tip colored gold for easier recognition. They are good because they start the arc quite easily and their burnoff rate is very low.


Their tip is colored brown. It is shown that this type can produce a very stable arc that can be very useful. This electrode is only usable for AC welding.


If you want to find a rare-earth electrode look for a tip that is colored gray. This is made out of combining Tungsten with some oxides.


Tungsten – Metal that lights the world

Tungsten – Metal that lights the world

Tungsten is a metal gained from mineral mining (wolframite and scheelite) and through recycling of the same metal. This metal on its own has some very high-profile uses, and as an element in an alloy, it becomes part of items that are widely utilized in all spheres of economy.

The typical Tungsten metal uses

Tungsten alloys3Tungsten has been around us for more than 100 years, and it is still a widespread element as its powder is the central component of a light bulb. The powder is heated at high temperatures with some other components to create a wire filament which produces light with the help of electricity.
This metal is dense and fire-resistant, and thus it has many uses like being utilized in the manufacture of lamps, microwave ovens and other heating elements due to its ability to keep the shape even under extreme temperatures. Due to its density, tungsten is used for weights, darts, fishing sinkers and similar stuff.

Tungsten Carbide – a robust and durable alloy

Tungsten alloys2The process of production of this metal is long as it has to be turned into a powder and then mixed with carbon, either (1:1 or 2:1 ratio) and heated up to 2900 Fahrenheit with hydrogen gas. It’s just slightly less hard than the diamond, and thus they sinter it to create the metal that can be used for the production of various elements and tools. You will find that the majority of drill bits and milling cutters, among many other things) are made out of this alloy due to its hardness and availability (compared to diamond).
Combine Tungsten Carbine and Cobalt powder, and you will get Cemented Carbine which is perfect for manufacturing of tools that are highly resistant to wear. The majority of large-scale machines and tools in mining industry use this alloy.

Standard alloys in which you can find Tungsten

Tungsten alloys1Mix Tungsten, Chromium and Cobalt and you will get Stellite, a durable and wear-resistant alloy that is widely used in the production of pistons and bearings.
Sinter the Tungsten alloy and create powder out of it and you get Hevimet, which is extensively utilized in the creation of ammunition (armor-piercing).
Eighteen percent of sturdy Steel alloy is the Tungsten, and it provides resistance to corrosion and wears to it. You can find this fusion in tools that are used for high-speed cutting (high-duty saw blades).

Tungsten – A metal that changed the world

This might not be obvious, but this metal and its alloys changed the world, and it is still changing it. IT has been in light bulbs from the moment we learned how to create them. It also replaced diamond for drilling which reduced the cost of mining and improved the overall state of the industry.
