Babbitt???

I bought a 35 lb ingot from a small scrap dealer on Saturday.
I seemed to be pretty hard and I took it today to a yard that had a metal gun.
.52 CU
1.06 SN
15.39 SB
82.46 PB
Am I correct in assuming some sort of Babbitt alloy?
I figured it might be good at sweetening my big melts of range lead.
Thanks

It sounds to me like scrap linotype, with the tin depleted, or in very small quantity. It will certainly sweeten range lead; I'd add a half-pound spool of 95/5 tin/antimony solder to the melt and you're ready to go. Then mix as linotype.

Hers a picture of the ingot.
The first letter looks like a Y to me but who knows.
Thanks

It could be a Babbitt of some sort, there certainly is no set recipe for it. With over 3% more Sb than lino I wouldn't cast it as is but yep it sure would sweeten a pot of softer alloy.

This is a list of what Rotometals currently sells as babbit. Number 4 Hardware is similar, but lacks any copper.

There was an article someplace some years back on different types of babbit that someone posted. There are about a gazillion mixtures and some contains no lead to speak of. I may have it bookmarked. I'll look if I remember.

That "#4 Hardware" babbitt listed in Joshua's post text looks a whole lot like the O/P's metal composition, and both look a whole lot like Linotype (84/12/4) with tin burned off/reduced/whatever.

As I said, cut any of the Cu babitts by 40 and you get ~0.1% Cu in the mix. Before you cut it with 100% lead.

It’s hard to chisel a piece off of it.
It breaks into small slivers instead of a curl or chunk.

Use it like half-power Rotometals Superhard. Get some tin and treat up a couple hundred pounds of roofing lead with it.

I wouldn't get all worked up about it.
you got a rough idea what it is.
you got a rough idea what's in ww's too.
'pure lead' ain't always so either.

1. figure a 'close nuff' for whatever else you got on hand.
2. make some small ingots from the big one you got, throw them all together and make some projectiles.

continue looking for more stuff to repeat the above instructions.

I couldn’t have said it better.
I’m working on a 1000 lb counterweight now.
Going to go look at it tomorrow.
Thanks

Did a rough check on the counterweight, They are in the first stages of taking off the steel plate that encases it.
Appears real soft and he also has a XRF gun to verify content.
My guesstimate is close to 2000 lbs.
We’ll see soon.
