Michelle, There are many suppliers of titanium sheet. Most, if not
all, will have high minimums. Start as local as possible. Try the
Yellow Pages and search on line. If you can walk in, you can often
get help with smaller amounts of scrap. It is how we all started
years ago. When we buy our specially prepared sheet we have to
purchase many pounds of each size. It limits our stock. We have seen
a small amount of square Ti wire. It was made for shrapnel in air to
air missiles. It is very ugly. But, no jewelry type shaped wire. Nb &
Ti are notoriously difficult to draw(and expensive). Could it be
done? Yes. It would cost a great deal and thousands of feet would
have to be run.
Good luck, Bill

They are my favorite for small orders of those types of metals.
Titanium sheet up to 3" thick!! As for square and 1/2 round, I don’t
know, but I seriously doubt you’re going to find 1/2 rd. titanium…
Correct me if I’m wrong, but my reading on Niobium indicates that it
doesn’t work harden (it will but takes lots of work for it to happen)
very fast, so with that in mind what if you started with a suitably
sized round section wire and rolled it down to the required square or
1/2 round?
I know that to anneal the stuff you need a vacuum chamber and some
sort of heating system (is resistive heating enough?), but I’d
hazard that is outside the tool collection of 99% of us all!
(Although I do own a 14" diameter by 20" tall vacuum chamber and
associated pumps and do hickies.)
You are correct: the wire can be rolled to form. Even in patterned
rollers. Heat treating in a vacuum at 1200 C for one hour causes
complete recrystallization of material cold worked over 50%. This
must be performed in a high vacuum (1 x 10-4 minimum) or in a clean,
dry, inert gas.
Thank you very much for the you have given me on finding
Titanium sheet and Niobium and Titanium wire stock. I appreciate the
help and the ideas. I have bookmarked the metals website and after I
get the details worked out for the Ti sheet I need I will place an
order with them. I will also try making the Niobium wire as
suggested.
Thank you for taking the time to help me. I appreciate it.
