These weigh 21 pounds each and have two very small brass nuts cast into the top. Composition is supposed to be 95 pb-3 sb-2sn, they are fairly expensive at 7.00 each but waste after smelting would be next to none. Can one of the experts give me the BHN for this composition- after I cast ingots I will test the hardness to see if it jives.

HI,
What do they call those things?

I'm no expert, but the folks at http://www.lasc.us/CastBulletNotes.htm probably come close.

Extrapolating from the information on their site, I would guess your alloy will be close to, or a touch harder than, wheelweights.

Look at the cast bullet association http://www.castbulletassoc.org/downloads.shtml

Download their "Alloy calculator" Its really handy to figure out the stuff in your mix.

When you play with the numbers your ingots should be around 9.357 BHN. That is a real good mix for handuns. I mix up lead and WW 50/50 and it comes out real close to that.

I think that is a pretty good price, .33 a pound, 2% tin, nice and clean, I would probably buy all they had If I could afford it.

Boom Boom; I don't know what they call them, scrap lead to me!

ANeat; thanks I'll see how it checks against the tester, smelting now have 280 plus ingots but haven't made much of a dent in that pile of ww, have several different ingots from Viener Metals, some test at 10.5 and others are pure lead, trying to get caught up before I collect more.

The last lead I tested with a cabine tree tester that looked close to what you have tested at around 10bhn or about 20-1 lead on his chart.

Curious, who told you the composition was 95-3-2? If those are the true numbers for the alloy(the math works out) most of the hospital stuff I look at and test comes in at the same number. Other than the soft sheeting and some other hospital lead that tests a bit harder.

the guy I got it from had the numbers, when I saw the 2 % tin I thought it would be just the ticket. A couple of years ago I was given 50 pounds of the small isotope containers, I had a couple ingots stashed they are 12+ bhn

Done,426#ww,43# x-ray,16 #viener hex ingots
The #x-ray stuff tests @ 10.4 bhn right from the mold- same as my ww, they weigh 183 grs- same as ww. The Viener Metals hex ingots tested 14.3 bhn, weighed 177.3 grs

So the thing to do is visit the hospital X-ray tech and ask what they do with their's?

Looks good!

I have some of those (identical). They tested out at ~11 BHN for me on a lee tester, several days after smelting. My WW ingots batches measured out at ~12 BHN over the same time frame.

There is a local guy who sells these. Has tons of them. .35/lb or .25/lb in quantities over 1000lbs.

I appreciate your posting the composition.

Considering the current prices and scarcity of other alloy sources, $250 for a thousand pounds looks pretty good.
