pewter ingots
hey guys, i am looking at just buying some pewter ingots rather than hunting around, i figue 15 bucks is well worth saving 8 hours hunting. but i have some options, here are the anatomies of the different alloys
A/C - Pewter tin:92% anti:7.75% copper:.25% bismuth:0% R-92 - Pewter 92% 8% 0% 0% R-98 - Pewter 98% 0% 0.50% 1.5% wondering if i need to go with the 0% copper, or if a little would help. i also don't know anything about bismuth or how and if it affects lead. any knowledge would be better than none. i could also just buy pure tin for a few extra if that would be better, but i was thinking this already has the antimony needed. thanks

Copper serves the same purpose in lead alloys as Arsenic.
I use it in place of Arsenic (in the form of solder), when working with antimonial alloys that don't have any. If you're running low amounts of Antimony, it doesn't do much for you.
