And .02% cobalt-nickel used as a stabilizer.

You didn't get and cobalt or nickle, did ya?

My bet is that it isn't BeCu.

The analyzer I used, turns out, will not identify beryllium. That's my fault as I'm not a chemist nor a metallurgist. I just have access to this analyzer. It does do a real good job on nickel and cobalt and it did not list either of those in the scanning that I did yesterday and today.

Then again, maybe the half-life of the source is getting old and is pretty weak....

you gave it your best shot so (IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif) : to you (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

Do you know what Radioisotope source was used in the analyzer? Different sources detect different elements. If yours is set up mainly for detecting steels, then it won't be ideal for analyzing copper alloys, and doesn't look like it will detect tin at all. This is important because another possibility for the diaphragm material is phosphor bronze, which should have large amounts of tin.

I was just looking at the label's this afternoon, but I do not remember what it said. C-10 seems to stick in my mind, I'll look tomorrow and report back.

I do know it only has one radioisotope installed in the unit and we use it mainly for verifying piping, vessels, welds, etc. at the refinery to make sure the right material is being used.

If you look at my original post, you'll see the display also contained other information, for example:

99.78% Cu
Elec Cu
Al, Si Br
Phos Brz.

Hootus hardness.... (IMG:http://www.914world.com/bbs2/html/emoticons/w00t.gif) That's freaking funny I don't care who you are.
We shoould have a virtual Hootus hardness contest.
Like the 914Cup. everybody can make shit up about how hard there hootus is and how long it lasts.

Well I called the Fuel Injection company (who bought out Bret Instruments) and the fellow over there, apparently the owner said that their diaphrams are copper, not a berillum-copper alloy. Or at least that what he conveyed by his explaination.

I'm gonna ask one more time then I'm gonna shut up...

Has anyone tested the hardness?

Is it dead soft? Quarter hard? Half hard? Full hard?

Is it a spring or a maleable piece of material?

And.... if the hardness is known, you might REALLY narrow down yer choices of what materials it could be...

I also want to thank RustyWa for having the initiative to give it a try with his equipment at work. Sorry it didn't work out. My thanks to you again. It is effort like this that will get the material known (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

can I help in anyway?

I have two good diapragms (OE) that I can use to help....

its a springy material, definately not something that would seem to work harden very easily (for obvious reasons)

I can probably measure the hardness in vickers. We use this in the gravure industry to measure the hardness of the copper plated cylinders we use. Maybe Britt can send me one of his. The test will not harm it. PM me if interested.

and from vickers we can get a approx Rockwell hardness....and from that we cna convert to Hootus Hardness.

it all works out.

we need a hootus standard though.... hmmm
