Nice!
Nickel goes cheaply too!

It's GR5 Ti alloy, which means 90% Ti, 6% Al, and 4% V. Just so everyone's aware of that.

A tip for people scoring Ti and alloys on ebay: get the size you want, unless it's thin enough to cut easily. My dremel with thin cut off disks was having a hellofa time cutting 1/16" sheet. Several (5) to cut about 7 linear inches.

I saw the cost of some thicker plates and sheet, like 1/4" - 1/2", thought it was a bit much compared to larger blocks. I then noticed some big blocks going for a relatively low cost for the amount of Ti presented. So reasoned I could get bigger blocks, take to the local machine shop and have them slice it like bread, sell off a few to cover costs. Leaving me with basically free material of my choice size. Deffinitely NOT how it worked out.

The machine shop guy said no way, but he could order what I wanted. Otherwise it was necessary to find a hydrojet equipped shop, pay by the inch, weeks of wait time and then try to recoupe my costs... So I have $100 worth of Grade 5 (6-Al,4-V) sitting on a shelf. somewhere near 16 lbs, a respectable sum for the two blocks :) pics are fourth post down- https://www.sciencemadness.org/whisper/viewthread.php?tid=26...

I did call and the nearest hydrojet guy was a little over an hour away, charged $3/in and had a two week wait time. Maybe I'll think of something to use it for worth the time/cost one of these days... so bear in mind it isn't something easily parted out or fabricated in general for an amateur w/ limited tools and money.

if you are collecting. go for Gr1 or sponge if you can find any. and buyer beware of getting fake purity out of china. there are good suppliers in CN but they are not on ebay

Is it possible to anneal the stuff to soften it up?
if you want to make electrodes from it softening it would make it easier to cut to shape.

I thought TC4 was low oxygen and considered commercially pure Ti. I failed to find any reference for GR5.

I checked some different references and you are correct about the composition. I guess that aluminium would reduce its corrosion resistance. How suitable it is for electrolysis or molten metals I do not know.

I have 1.5 mm sheet CP grade 2 that I can shear to size for whomever wants. Used to have a lot more but sold most all of it. Regretting that now.

$10/square foot + shipping and $1.50/cut (it does work harden and I have to sharpen the shear blades).

Gr5 (Grade 5) is in the listing name.



Grade 2 here

http://www.ebay.co.uk/itm/Titanium-Ti-Gr2-Grade-2-ASTM-B265-...

This thickness of stuff is too thin as cathodes and has failed when used in chlorate etc cells


Canadian supplier here
