Niobium ( Chemical symbol : Nb ) stems .
I've been searching for Niobium tubing for some time ,now .
No luck at all.
Very difficult to find that material first place,let alone in tube form.
Well ,the universe -actually was George himself -responded to my humble re-quest ...

Also in the package, you will find something else I have been very anxious to experiment with. 10x1mm Niobium tube. This was a challenge to source, and I haven't had the focus to do what you are doing, so I hope you will be able to make something interesting with it. It is supposed to color better than Ti. I think I labeled it, and it is slightly heavier then the Ti with a slightly darker color. "

Niobium is heavier than Titanium.
It gets anodised in same hues like Titanium ,
but the same hues are somewhat more vivid /vibrant than of Titanium .
It's very rare to find at tube form .VERY-VERY difficult to source !
And four times more expensive than Titanium .
And almost eight times more expensive than Copper .

Right now ,thanx to George I've in stock about 1000 mm of
8mm ID /10 mm OD " Nb " tubing .
Or to put it in other forms :
A ) 16x 62 mm standard Niobium stems
or
B ) ~12x 79 mm XL stems.
I really haven't decided which length will prevail,here.
What matters most is that some really rare textured and anodised Niobium stems are going to be made.
Few of them,for now at least.
More about Niobium stems ,as soon as I 'll start working with Niobium tubing.
Cheers.
