X-ray of lead

I doupt you can x ray lead. It is used as a shield for x ray...
What do you want to acheive ? Unless you have a really BIG stack of all the same type - it’s useless.
 
I'll be following this thread with interest - from the old school that only knew about documenting melting and freezing temperature of alloy, checking Brinell hardness to get guesstimate of what sample actually was - then diluting, or blending, as needed, with something known to have better numbers, to get to desired target. I am presuming your tests can tell you % composition of the test material??
 
From the last batch I sent in.


1. Allen's ingot.
2. Odds & ends lead
3. Mystery 50/50
4.Berts ingot

Sample #1

Pb = 0%
Sb = 3.9%
Sn = 90.1%
Cu = 6.0%

Sample #2
Pb = 93.0%
Sb = 3.7%
Sn = 3.3%

Sample #3
Pb = 94.4%
Sb = 4.4%
Sn = 1.2%

Sample #4
Pb = 95.3%
Sb = 2.6%
Sn = 2.1%

It's not a traditional x ray. It is likely one of these from Thermo Scientific. My buddy has one for use in his scrap yard. His model was $30,000 a few years back. Point and shoot and you get a very accurate reading instantly. A few years back we bought it to test gold and platinum group metals we recovered and refined. All from gold and platinum bearing scrap collected over 40+ years. Old school General Electric CNC machines were literally gold mines. Made a god damn fortune...$$$

I cant remember what nuclear element it uses, but its nasty enough to penetrate lead and has to be licensed with the Nuclear Safety Commission of Canada.

Thanks for doing this, very interesting.

JC5 was my 20 to 1 mixture I use for my Sharps 45-70 black powder loads, I am close and only need to adjust slightly as I am coming in with a brinell hardness from a lee hardness tester at about 11 and 20 to 1 is about 10.

JC1 was 1970's clip on WW with 2% tin added. Looks like I am really close on that one also. I have heard that the 70's WW had a lot of antimony in them and it looks like they were correct. I was given some 20 gallon pails about 5 years ago from a 70's gas station that has been dormant for 40 years. A builder decided to redesign and make it into a dentist office and my cousin was the contractor who did the work and asked if I wanted these old pails of WW's that he found.
