While going around in scrapyards to gain some metals for knifemaking, someone gave me this block. I like so much it's appearance. It's like Ti in surface but can be some Alluminium or some rare other alloy.
Really don't know if it is Ti, Al or some strange alloy. Those guy says to me that it is an ingot of very expensive alloy for mil and/or aereo use.
Maybe useful for some fancy and scales once sawed...
Someone can guess what it is??

Here some pics:

Some of those numbers make it look like 64v TI, grind it, white bright sparks will tell you if it is.

thanks for info Richard.
Maybe some one can help to solve this puzzle without atomisation?
 
If you can provide the dimensions and weight, the density could be calculated. That would probably be the quickest and easiest way to get a rough idea of what it might be.

Following JC's thought, here is how you calculate density.

D (density) = M (mass) / [L (length) x W (width) x H (height)]

M = W (weight) / g(9.8 m/s/s or 32.2 ft/s/s) [depending on metric or english]

Remembe to convert weight into mass before you calculate, or it could screw up your answer.
 
Just curious, which numbers make you think it is 6al4v? The missing right hand side would be a lovely find and would reveal a lot. The stencils are classic US Dept of Defense. Although with missing letters the abbreviations could mean anything.

I agree with the assesment that it is probably Titanium and the spark test should confirm this. You could also look up the heat treating temperatures for 6AL4V titanium and see if you can heat treat your metal. Be very careful of what you pick up in a junk yard, there are some things that are very dangerous that people discard. Radioactive materials have been known to find their way there as well as sodium filled jack hammer bits (they have been known to explode when placed in a forge) and items made of copper berrilium which you don't want to use since it is highly carcinogenic.

im 70 % sure that is 6AL4v Titanium 3 test's will confirm it #1 grind it you will get a very bright white spark
#2 put the strongest acid you can on it ( Battery) acid or acid gor testing gold
#3 anodize it only Ti or niobium will color you only need 20 volt's to easily see the color change ..it look's like a pretty big piece i would cut a strip off with a metal cutting bandsaw and do my test's on the strip i cut ..

mmmm.
you're right.
I,ve to do some test at the soonest.
If it's really some 6AL4v Ti i think i've found something interesting isn't it?
:cool:
 
mostho,

What it appears to be is the end of a Ti ingot. A quick spark test as mentioned earlier recommended will confirm. If you want to slab it do it with a bandsaw, waterjet will be cost a bundle. The ingot plant I am near use saws to do their heavy cutting work. Waterjet are for cutting shapes from sheet, bar and plate not ingot conversion. I've been in the Ti ingot scrap yard more than a few times and you would be surprised of all the cool stuff, but it may glow in the dark, be carful.

I had a Ti Ingot guy stop in the shop today and showed him your picture and he also estimates the block you have looks to be Ti Ingot. Probable 6AL 4V by the looks of the second line of markings.
He said scrap Ti prices have been going up and is about $7 lb/US.
Being a stub from an Ingot it probably has not seen anything that would make it glow in the dark.

I just looked back through the thread and couldn't find any dimensions listed. There is nothing really in the pictures that can be compared for size. And at $7 a pound I hope it weighs a ton!
