Tungsten

You have "Standard" and "Wolfram" tungsten options. What is the difference and why does Wolfram cost much more?

All DGP tungsten is high-quality tungsten that comes with material certifications and MSDS sheets to prove it. We proudly stand behind all have confidence in every piece of tungsten that we sell.

Wolfram tungsten, manufactured in Germany, is the top-of-the line of tungsten. It is the Porsche of the industry. So while others tungsten we carry could be considered a Ford F-150 (Silverado for you Chevy die-hards) in that it is a consistent, reliable & quality tungsten, the Wolfram tungsten is held to the most stringent of standards. That is why you often see Wolfram tungsten offered at what can be considered a “premium price”.

What is E3 Tungsten?

What E3 is seems to be is a bit of a mystery. E3 tungsten is a Tri-Mix imitation manufactured in China.  However, it has a purple band, which according to the AWS is 3% Thoriated tungsten. It is often offered as an alternative to 2% Thoriated.  However, any claims of it being “required” because 2% Thoriated is being discontinued is incorrect.

Is 2% Thoriated Tungsten being discontinued as some competitive manufacturers claim?

No, 2% Thoriated Tungsten is still being produced and is still the most used tungsten on the planet.

No, these are all Tri-Mix copies that are made in China. You can only get Tri-Mix tungsten from Diamond Ground Products and our distributors.

If you’re ever not sure what you are buying or where it is coming from, simply ask for material certifications. If the company won’t give you them, you may want to avoid them.
