Syracuse Government Genuine Babbitt Alloy

[Gasman 15]

I found 2 bars of this alloy. It appears to be

89% tin
8% antimony
3% copper

Does anyone know if this Can be used to harden lead for casting bullets?

[Markopolo]

Possibly.. a small percentage will help with mold fillout. Depends on what your alloy is.

You have #2 Babbitt

[Peregrine]

Possibly..

Possibly??
Definitely.

I just scored some similar Babbit last week, I put about an ounce in a lee 20lb pot of range scrap and cast some of the best bullets you could want. Regards Stephen

Definitely harder, but only by using a lot of tin which many might prefer to use sparingly for better fill out in their alloys. Perhaps save the Babbit and use antimony for the hardening?

[Gasman 15]

I have some ingots that I make fishing weights from that is pretty soft(similar to wheel weights). I’d like to harden up this unknown alloy to make it suitable for gas checked magnum loads. Any advice

[Tom W.]

Just don't use it alone. It will make great , light and too hard boolits. I still have some Ni. Babbitt cast into a cast iron corncob pan. I may use 1/8 of an ingot in my 20 lb Lee pot.

You have some good stuff and it is defiantly useful. It won't take very much, probably less than you would think. A member here designed an alloy calculator thats free and available to download. It has a small learning curve but you could download it and it will give you the necessary amount to add.

I can't seem to find the alloy calculator. Can someone kindly share the link? Thanks in advance

[lightman]

Its in the stickies at the top of this page. About the 5th or 6th one down.

I've used similar to mix up homemade Lyman #2 based on the lead calculator.
