Welding aluminum isn't that easy that we think. If you need your welding to be your expected result, then you need to practice more and more.
It also depends on the metal thickness, your chosen machine, the settings of this machine, and the tungsten.
So that, you can improve your travel speed and a good penetration as you expected.
On the other hand, you need a welder that is good for weld aluminum.
Now, we're going to be discussing all that's on a need-to-know basis when it comes to picking out the best tungsten electrode for your welder.
Below we talk about 5 best tungsten for aluminum, types of tungsten and many more.

Types of Tungsten for TIG welding Aluminium
Pure Tungsten-Color Code: Green
99.5% of these particular electrodes is just tungsten. They are relatively on the cheaper end and demand a lot more power than the others.
People typically use these when dealing with alternating current(AC) welding with a balanced wave because they give us great arc stability.
The same is true for AC Sine welding primarily on aluminum and magnesium.
When heated, they form a clean, rounded tip which is exactly what we need when welding aluminum.
Zirconiated-Color Code: Brown
Zirconiated tungsten electrode composition: at least 99.1% tungsten and about 0.15% - 0.4% zirconium. It's ideal for AC welding.
Ceriated Tungsten-Color Code: Orange
Ceriated tungsten electrode (2% Ceriated) composition: at least 97.3% tungsten and about 1.8% - 2.2% cerium.
It's great for DC welding current levels set at low but also good for AC welding.
Rare Earth Tungsten-Color Code: Gray
Rare earth tungsten electrodes are composed of different combinations of rare earth oxides that can come together to provide different results for both AC and DC welding processes according to what's in them.
Lanthanated Tungsten-Color Code: Gold
Lanthanated tungsten electrode (1.5% Lanthanated) composition: at least 97.8% tungsten and about 1.3% - 1.7% langthanum or lanthana.
It's good for both alternating current(AC) and direct current(DC) welding.
We'll get more into detail about these particular electrodes in another section where we will compare them with thoriated tungsten ones.
Thoriated Tungsten-Color Code: Red
Thoriated tungsten electrode (2% thoriated) composition: at least 97.3% tungsten and about 1.7% - 2.2% thorium.
It's also good for both AC and DC welding which really begs the question; Lanthanated or Thoriated?
Stick around as we discuss this in the 'Lanthanated vs Thoriated' section of this piece.
Now, we have mentioned all lot of tungsten electrode variants and I bet you are wondering what now?
You are still lost as to which one to choose, so now we are going to help narrow down your options by looking at what you should be looking for when you choose your ideal tungsten:
The first thing
You should consider is the diameter of the tungsten electrode you are going to use as we already know that in the AC welding process a lot of heat is absorbed by the tungsten.
Therefore, you will need a larger diameter to absorb as much as possible.
It's advised that you do not use thoriated tungsten electrodes when using a conventional power supply because when you heat them and the tip starts rounding over, a few small deformities appear on it and ultimately it leads to the arc being rather unbalanced.
We recommend sticking to pure tungsten or zirconiated tungsten electrodes.
Ceriated and Lanthanated tungsten electrodes are also a good choice what with them being able to work well on Both AC and DC processes.
Another added bonus is that they are not radioactive and that is always good!
The only downside is the price, so if you are planning on sporting one of these babies, be prepared to take out that ol' piggy bank and get to spending.
But if you choose to use the more modern inverter power supplies then you should use thoriated tungsten and you can grind the tip to a point.
Lanthanated vs Thoriated
Straight off the bat, We'd like to say that we highly recommend 1.5 %lanthanated tungsten electrodes over thoriated ones for a number of reasons:
- Well, first of all, Lanthanated Tungsten can take more amperage than any other alloy on the market.
- Also, Lanthanated Tungsten does not discriminate when it comes to which type of machine you choose to use. In other words, it is compatible with all types of machines.
- It uses the least voltage in order to be broken down. This means it starts arc very easily. It does it better than any other alloy.
- Lastly, Lanthanated Tungsten is not radioactive unlike thoriated tungsten and some of the others.
- Well, Lanthanated tungsten is not very easy to find. Most local welding shops do not have it.
- Needs more time and effort when grinding.
- Lastly, Lanthanated Tungsten costs a bit more than other options which really, may or not be a problem for you.
Anyway, I feel we should filter the options even more by listing our picks for the best tungsten electrodes for aluminum on the market.
So What's The Verdict...
If you are looking for the best tungsten electrode, I like any other metal enthusiast would tell you that no tungsten electrode does it better than 2% lanthanated tungsten electrode Farewell.
