Titanium fabrications

Would you like my address and when you deliver the starter to me I can shake you by the hand (or neck) and show my appreciation for very kind contribution to my cause.
lol, hmmm. Let me think about it for a while.
Regarding the fabrication; what is it youre looking to make? Does it require welding?

I must say when I first saw your reply, I didn't get it! Then I read my post
I intend to have things like pedals, steering column, latch pins and small incidentals replicated in titanium so yes, some welding will be required I would think.
Titanium fabrication can be done, but it is more commonly used in processes such as sintering and casting.
With steel or ally you get a block of the good stuff and rip away until it's the shape you want. Both can be easily obtained, as bar stock and extruded sections, but with Ti it's not quite like that.
Ti can be welded, but it must be done in particularly clean environments, possibly oxygen free to prevent it from becoming brittle.
Think regular annealing, and making things like angle by folding sheet.
With ally or steel, you have a drawing, and just use a different material. When you use Ti, you have a whole different philosophy. Each stage of the production process is micromanaged, to mitigate the problems that using the material creates.
Think of Ti as being a pain to use, but a godsend if you have a very difficult problem. If you want things like Ti con rods, you'll be better off I'm sure buying them off the shelf. If you want a Ti chassis, for peace of mind, just make it out of ally.
Edited to add;
It's probably quite good for grinding!

I hope you manage to find a sense of humour when you see the prices for one off titanium fabrication !
I have just spent 5 long years building my Ultima, of course I have a sense of humour! (see post above). I did try to add a smiley to the 'neck' re post but for some reason it did not work.
, typical, it bloody works NOW!When we were making our Formula Student car one of the teams used titanium for all their wishbones and uprights, however the problem is as soon as you machine it it loses a lot of its sought after qualities i.e strength and toughness for its light weight. You have to do a lot of heat treatment to get it back to its un-machined state. They even said afterwards that it was a real waste of time and money.
Unless you are planning to get it casted into shape
which will be hideously expensive then i am guessing you will need to have it machined.
I know this is not very helpful in terms of what you asked e.g suppliers, but titanium isn't necessarily all its cracked up to be depending on how you utilise it.
Why not try a very high grade alumnium especially for pedals and steering components, aluminium is very undervalued in terms of its properties, if you get some that has been heat treated properly and of a good grade it can be VERY strong and tough.

Depending on what applications you are using Ti for, I would go down the aluminium alloy route personally, because with titanium its either all or nothing with regards to costing. You need to find a fabricator who specialises in Ti fabrication and has a lot of experience, because as previously stated, Ti can lose a lot of its properties when its not fabricated under the correct conditions or in the correct fashion.
The gains you will get from using Ti will be outweighed by the costs you pay for it to be fabricated. It is much better (if you can) to buy off-the-shelf products.
