The Usage Of The Tungsten Across The Industry

The Usage Of The Tungsten Across The Industry

Tungsten is a metal that is well-known for its properties, and many countries and industries seek it. It possesses features that make it useful in a lot of various professions, and the only limiting factor is the discrepancy between supply and demand. The request for this metal is high but the supply is limited, and thus this metal isn’t widely spread as it should be due to its attributes. Even though the supply is limited, this metal is still used in some alloys spread across the industry.

Typical uses of the tungsten and its alloys

The most common use of this metal is in alloys where it usually plays a support role. This means that the benefits of this element are added to create an alloy that profits from those advantages. There are several benefits that tungsten provides that include resistance to heat, wear, and corrosion. High-speed steel is an alloy that has up to 18% of this element. This new metal is used to make saws and other machinery that has to suffer a lot of wear. Alloys that contain tungsten are several times more durable than those that have other elements. Tungsten Alloy has a reputation of being one of the best materials when it comes to creating electric relays and contacts.

Tungsten, in one of its forms, is also used to create hard and durable alloys. The final result is a metal that won’t succumb to pressure, heat, corrosion, and wear. It’s mainly used for large-scale tools that are quite expensive but can last up to a decade with little maintenance. This metal, in alloys that focus on other elements, plays a significant role in the building industry, even though they aren’t a cheap option to choose.

Alternative uses for this precious metal

We already mentioned some mainstream uses of the tungsten, but we shouldn’t forget other industries that seek this material. The military is one of the parties that require a large quantity of this element due to its properties. It’s used to make kinetic energy penetrators which make uranium obsolete as it isn’t radioactive as metal above. It’s also well-known that various armies use tungsten in the production of shells and other exploding armament as it can create supersonic shrapnel which is deadly to infantry. It also increases armor penetration of short-range shells which enhances the ability of small calibers to do critical damage to armored vehicles.

The density of this metal makes it perfect for counterweights, weights, and ballast for a variety of sea and air vehicles. The problem that these industries encounter is the lack, and the price of the said material as other industries have an advantage when acquiring it. Formula One and NASCAR are only two racing sports that use this metal regularly.

Tungsten – A metal everyone wants

Tungsten is still an element that is in high demand, and it will stay like that shortly as well. If it were easy to manufacture it, then many problems that plague economies and industries would be gone. This metal has the power to change the world, but that won’t happen due to its rarity.

 

 

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.

Thoriated

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.

Ceriated

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.

Lanthanated

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.

Zirconiated

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.

Rare-Earth

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.
