Suggestions please !

They haven't any at B+Q or Screwfix, so who can supply a 18" x 3 " x
18 gauge strip of titanium ?

Thanks


Try doing a simple Google search for titanium sheet. I got loads of
suppliers in different areas.

British Aerospace have got shed loads. Give them a call.

Hi Give your local Steel Stockist a call. Ask them who they supply, and
give them a call and see if they can supply you with a offcut ?

Tried that, but the ones I spotted were looking at 600 x 2000 mm sheets...

Its the small pieces problem that has me beat. I can get industrial
quantities.

E-mail to the makers will probably get you an off cut cheap enough.

I never cease to be amazed at the number of people who seem reluctant to
pick up the telephone and ask if it's possible to get hold of small
quantities from a supplier, but they're quite happy to ask here.

Firstly, as I understand it, titanium comes in a variety of
grades. Are you attempting something like rocket science or does
this not matter as you only want the appearance? Titanium wa
quite expensive a few years back because so much of it was going
into sporting bats of one sort or another and the law of supply
and demand came into play. Depending on purity and grade you are
looking at UKP 1 per gram upwards in small quantity.

Newmet Koch 01922 703400

do all sorts of exotic metals. Depending on the metal, they go up
to six nines purity. Small orders no problem.

I never cease to be amazed by people who make unwarranted assumptions -
a run on the phone got me prices of 200 quid MOQ from 5 stockists, 1 in
Manchester 4 in the Midlands. Hence I asked here as a last resort.

John, Thanks for your help. The application is an ornamental one, so the
exact grade and putity is unimportant. Mostly I have been offered G5,
but I have no idea if that is good bad or indifferent. I want to
decorate the piece by anodising.

Why get Titanium then coat it?

Anodising isn't quite the same as coating. You still have the
same outer layer of titanium oxide, but you have dye molecules
diffused within the oxide layer, so it's coloured. It's just as
hard as it was before.

You don't have to go all that thin to get interference - also
works with smooth anodised aluminium.

That depends who you ask ! Bit of a controversial claim at the

The colour effects are very neat, and the stuff is hypo allergenic.

True, I think it must be related then to the natural lustre/colour of
the metal, you certainly get stronger contrasts in Ti.

Since I have two 16mm pieces in my jaw now, I bloody well hope it IS
hypo-allergenic !

With anodised aluminium, it is a synthetic dye adsorbed onto the
surface that gives it the colour, effectively a lake. (q.v.)
Anodised titanium works on film thickness, but is fairly
complicated to achieve a predictable colour without a lot of
(expensive) trial and error. Current, duration, electrolyte and
so on all have an influence. Had I realised this was the path you
were going down, I'd have suggested (DIY ideals notwithstanding)
that you buy the stuff ready coloured.

Hi John,

You are always a mine of information for exotic processes !

I do have the tackle to play with the anodising process, for Ti, it
takes quite a high voltage, and you need to pickle the metal before
treatment - the preferred pickle until recently contained HF acid, but
that has been dispensed with. Repeatibility isn't really an issue.

I have finally found a Ti supplier in the USA that supplies what I want
for around 12p / sq. in, as opposed to the £5.00 sq in I have been
quoted here. www.reactivemetals.com for interest.
