Hello Rick, Please do not speak about gauche, it is so old fashion
and difficult to understand in the rest of the world. I have looked it
up and 20 gauche seems to be 1 millimetres. You can buy at nearly at
every big industrial supplier, titanium up to 20 millimetres If you
face trouble in this I can also be helpful, I live in the Netherlands
and the titanium can be trough shipping more expensive than were you
live. But if you need only a little bit, I have square 6 mm, and 1
1,2 1,5 and 2 mm sheet. Also round wire from 1.5 up to 5 mm I can buy
from 0.5 up to round 50 mm. and al kind of tubes.
The reason there is not much to buy in small sizes, is that there is
no much industrial need for. And we jewellers buy compared to the
I do not know if you have a rolling mill you can easy roll down to
0.2 mm. (some clowing is neccesary, dull red) However I do not succeed
in drawing down titanium, not even in Tungsten drawplates. I know now
why wire below 1.5 mm is so expensive. But maybe someone else has
better success in this, and is willing to share this with me.
