paiva Posted May 16, 2016 Report Share Posted May 16, 2016 Any recommendation for any metal available on the market that is around 25% less dense then lead and a still good metal, or metal mix combination, that will be good for pouring jigs? thank you in advance Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted May 16, 2016 Report Share Posted May 16, 2016 60/40 solder has a density of 8.5g/cm3 which is roughly 25% less than lead. Here is a useful link. Dave 1 Quote Link to comment Share on other sites More sharing options...
cadman Posted May 17, 2016 Report Share Posted May 17, 2016 You can also use bismuth. There are different alloys available, or you can mix your own alloys to create your density that you want to use. 1 Quote Link to comment Share on other sites More sharing options...

dan tinman Posted May 29, 2016 Report Share Posted May 29, 2016 Tin is your best bet. 33% lighter than lead and melts at a much lower temperature. Only down side is it's expensive. Depending on how much you buy at a time it can run between $14 to $20 per pound. Scrap yards will sometimes have it at a much lower price.
