It is one of the alloys used to make Bismuth shot for hunting
Less than 10% tin and the shot has a nasty habit of cracking in 1/2
When one of the places loading the shot close up years back , I bought all I could afford and have loaded and used most of the shot for duck hunting through 2 old Winchester SXS's that were produced before steel shot was ever thought of

Bi replaces Sb in a PB alloy up to about 2% or so.
I'd just look at their super tough or super hard if you need to make some alloy to cast with.
