copper hard babbit metal

[guncheese]

i just bought a 6lb 7oz. ingot of
Neylite Babbitt Metal - 300B Elements: Pb 45.25% Sn 37.75% Sb 14.75% Cu 2.25% Balance Others 0.50%
for what i think was a okay price $45 shipped
i broke it down
2.43lb SN
.95 lb SB
2.91lb PB

i know superhard is $4/lb

but at Roto's price its $68 worth of constituent metals

did i do ok?

and whatever will i do with it

no i just have to find some dead soft or stickon or maybe iso lead

really i dont know why i bought it
as the The Captain has been getting me coww and soww that works mighty fine

maybe i have a highspeed propshaft i have to pour bearings for that i dont know about!!

There is a whole thread here on hardening and toughening alloy with babbit containing Cu.
High Copper Alloys- Lets discuss this further

I add RotoMetals #3 babbit into my rifle boolit alloys. It would be a little over kill in a hand gun alloy.

[guncheese]

it may have been stoopid to buy it
as i just run powder coated range scrap mostly anyway
i guess i need to come up with some dead soft and work it into a usable alloy
and thats gonna take alot of dead soft!

That is some stiff babbitt. What were they using it in?

[GabbyM]

I'd blend it with wheel weights. Should work good. You have more Sn than Sb so you want a metal with more Sb than Sn so you can get to around even amounts or less Sn than Sb. I'd start with 1% of your Babbitt into WW metal then see what you have. You'll probably end p using around 2% into WW. There is a bullet metal alloy calculator here on the site somewhere.

[guncheese]

yes i think its going to be a real bit of work to get some sort of proper proportions with this stuff
ill save it for rifle bullets
but even then ill be powder coating
maybe i need to buy a old car or tractor so i can pour some bearings!!
ive been messing with the alloy calcs

[bangerjim]

That stuff will work great for harder boolits! There are over 40 different alloys called babbit. I have 4 of them and by using the free alloy calc spreadsheet on here, you can work them into your mix as needed. Download it.

Or sell it. At least you know the exact content. Not just "I have some hard lead my fingernail cannot scratch" like we hear all the time. If in it's original marked foundry bar, leave it that way!

+1 on use it as some sweetener for some rifle bullets where you want to push the velocity.

If you get some superhard, here is one possibility:
1 lb superhard + 10 lbs SOWW + 0.25 lbs babbit = alloy with @ 1% tin, 3% antimony
(the copper is negligible at 0.05%)

Without the babbit, the above alloy would be @ 0.25% tin, 2.75% antimony.

fiddling with one of the alloy calcs
if i skip the superhard
and go with 10lb COWW and .4lbs of my babbit i get

Tin %	Antimony %	Arsenic %	Copper %	Silver %	Lead %	Weight	Est. Hardness
1.93%	3.45%	0.24%	0.09%	0.00%	94.3%	10.4	12.3

that should do well for most anything i mess with and even cast pretty decent as well
and maybe even un checked midrange rifle since i powder coat everything
i just dont want to waste SN trying to get SB in it

but back to superhard
if we take all of my babbit and 10lbs of superhard i think we are talkin something useful

Tin %	Antimony %	Arsenic %	Copper %	Silver %	Lead %	Weight	Est. Hardness
14.77%	24.03%	0.00%	0.88%	0.00%	60.3%	16.4	35.0

that looks like a good stiffener for 100lbs of SOWW

[bumpo628]

Or you could go 5 lbs SOWW & 5 lbs COWW in the mix you just posted and get:
an alloy with 1.8% tin, 2% antimony

It all comes down to trying a couple mixes and seeing what works for you.

I used to get bearing Babbitt all the time for free. It was great stuff once you got the grease off. I would melt one weighed bullet in a Lyman dipper and add 20 grains of Babbitt to it until I got the desired hardness. Then use those proportions in my pot. I had 40 lbs of it stolen from along side of my garage one day. I wasn't upset because my supply was endless but now those days are gone and I wish I had it.
