For success in your home metal shop projects you need the best tungsten for aluminum. It's not just down to expertise and skill, but also the quality of the tools and materials you work with! When welding shop metals such as aluminum, steel, copper and alloys, a reliable join is important for welding with strength and integrity.
Are you looking for the best tungsten for aluminum? Let’s help you out!
Tungsten electrodes are a key non-consumable for DIY, student and ‘pro’ welding projects of all kinds. Tungsten Inert Gas (TIG) welding needs a tungsten electrode for joining the various metals. This electrode needs to be up to the task of conducting the current needed to create a welding arc with enough heat to melt and join the metals being worked on. For aluminum workers like boat builders, furniture makers, and trailer repairers, Gas Tungsten Arc Welding (GTAW) requires only the tungsten for aluminum which delivers the precision that you need for a great job.
Your buying guide for the tungsten for aluminum welding.
The key advantage of working with tungsten is that it will not be used up by the heat generated by your welding. However, other metals in the tungsten alloy will be consumed which leads to the gradual degradation of the electrode. Poor quality tungsten electrodes have a short lifespan (making things more pricey overall) and can often cause burn-off with the scorching of the welded metal.
When buying tungsten for aluminum work, you need to take a look at these key aspects of the electrode:
●The type of alloy you are using for your aluminum projects, choose from:
●2 percent thoriated tungsten electrode
●Newer rare-earth electrodes such as ceriated and lanthanated electrodes
2.The current you like to use.
Depending on your experience or preference you will need an electrode specifically for AC or DC current.
3.Finish and polishing.
A good quality electrode will either be chemically cleaned for a smooth finish or mechanically ground and polished for uniformity of size and good performance all the way through. This enhances the heat-conducting power of your electrode. You may also have to grind the electrode tip to a point, yourself.
Diameters vary depending on the type of welding undertaken with the smallest diameters used for fine, precision work. Most tungsten electrodes are available in diameters between 0.5 and 6.6mm with lengths up to 60 centimeters.
5.The type of welding torch your electrode will sit within a collect or chuck in the center of your welding torch. It must be firmly held in place, so you should ensure that the electrode and torch are compatible.
Our best tungsten for aluminum picks will hit all the points.
Read on for a helpful breakdown of the best tungsten electrodes on the market. If you are AC welding, larger diameter pure tungsten and zirconated tungsten electrodes are a great choice.

Will I need to grind my tungsten electrode tips myself?
You can let your tungsten electrode form a smooth round ball at its tip through use while you weld.
What does the color code on my tungsten electrode mean?
Tungsten welding electrodes are color-coded so you will know which type you are using. Here are the codes you need to know.
- Green = pure tungsten
- Gold = 1.5% lanthanated
- Blue = 2% lanthanated
- Red = thoriated
- Purple = rare earth
- Orange = ceriated
- Grey = rare earth
- Brown = zirconiated
Why does my aluminum weld seem to be less strong than the parent material?
If you are new to working with aluminum, remember that aluminum is a relatively soft metal and typically less dense and more malleable than other metals and alloys. These welds will always be weaker than the parent material and you will need to take this into consideration if you want a structurally strong join.
How should I store and maintain the welding electrodes?
Take good care of the tungsten for aluminum by storing it properly in a moisture-free, airtight container when not in use. This prevents corrosion and deterioration of the electrode point. Clean your electrode when it has cooled after every use. You can also sharpen the electrode at regular intervals to keep it in good shape.
What are the benefits of the metallic oxides in my welding electrode?
If you are welding with a tungsten alloy, the metal oxides present will improve the longevity and performance of the electrode.
Can my tungsten electrode break if I drop it?
Careful handling is essential when working with tungsten as if dropped it can develop minute splinters that are unnoticeable on superficial inspection. These can be dangerous if handled or if slivers of the electrode get into the eyes. Shattering and splintering will cause instability of the arc and defects in your welding.
If you love the versatility of aluminum welding projects, choose from the best tungsten for aluminum for electrodes to complete a precise and reliable job.
