cz75b Posted May 13, 2011 Report Share Posted May 13, 2011 http://www.lasc.us/Fryxell_Book_Contents.htm FYI for anyone interested in understanding lead and lead alloy use for casting. If you go backwards through the link, you will learn amazing things from the bullet casting community. If you don't question the claims that pure soft lead casts better after reading this, read it again! Enjoy..... Quote Link to comment Share on other sites More sharing options...

I read the section on Fluxing Lead, and found this sentence very interesting....."What’s more, as the sawdust chars on top of the melt, it forms activated carbon, which is a high surface area, porous sorbent material that has a large number of binding sites capable of binding Lewis acid cations like Ca, Zn and Al. So it not only keeps the tin reduced and in solution, but it effectively scavenges those impurities that raise the surface tension and viscosity of the alloy (Al, Zn and Ca), keeping the alloy in top shape for making good bullets." Sorry about the double post.... UG Edited May 13, 2011 by Uncle Grump Quote Link to comment Share on other sites More sharing options...

Ogajiga Posted May 13, 2011 Report Share Posted May 13, 2011 Yes, good info, especially the sawdust flux. Gotta be careful I suppose to avoid construction sawdust which might contain nasty wood treatment chemicals. Jig head & sinker casting alloy requirements aren't as exacting as bullets, but I found the tin-antimony 50-50 proportioning advantages possibly useful.
