mixing in Tin with pure lead - Reloaders Guide

Apr 15, 2010· 2. So what I'm hearing is (on an average), 30 lb pure to 1 lb tin would give me a hard enough plinking/target round. Also using 5 lb of pure lead mixed with 1 lb of wheel weight lead would also be a good choice. Gonna try both - starting with the second, since most all my ww and pure are in 1 …

What kind of solder (rosin cored, etc. lead-free)? What is ...

In tin-lead solder, the mixture has a lower melting point than either lead or tin alone, and the melting point varies depending on the portions. The mixture that yields the lowest melting point is called eutectic. This is also the only mix where all the constituents melt and freeze at the same temperature.

Solder - Wikipedia

Tin-lead (Sn-Pb) solders, also called soft solders, are commercially available with tin concentrations between 5% and 70% by weight. The greater the tin concentration, the greater the solder's tensile and shear strengths.Historically, lead has been widely believed to mitigate the formation of tin whiskers, though the precise mechanism for this is unknown.
