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?

Possibly.. a small percentage will help with mold fillout. Depends on what your alloy is.
You have #2 Babbitt
Possibly??Quote:

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?
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
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
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.
