Tin is more conductive. Lead is used to ease application.
to keep lead out of drinking water pipes.
The chemical formula for solder can vary depending on the type of solder being used, but a common formula is Sn (tin) mixed with Pb (lead), known as Sn-Pb solder. The ratio of tin to lead can differ, with common ratios being 60% tin and 40% lead (60/40 solder) or 63% tin and 37% lead (63/37 solder).
Solder
70/30 (70% tin, 30% lead) the more lead in an alloy the higher the melting point is.
No, lead solder is not a ferrous metal. Ferrous metals contain iron, while lead solder is primarily composed of tin and lead.
The compound symbol for solder can vary depending on the specific composition. Common solder compounds include tin-lead solder (Sn-Pb) and lead-free solder such as tin-silver-copper (Sn-Ag-Cu) or tin-copper (Sn-Cu).
It is a mixture
A Conductor, SOLDER IS NOT AN INSULATOR. The most common types of solder are made of tin and lead. Another type is silver solder. All of the materials used are metals and are good conductors of both heat and electricity. If you solder something you would notice if you ever held a wire (without protection) while applying solder to it your finger would probably receive a burn (speaking from experience).
Traditional electronics solder also contains resin.

Solder
Soder used to be made of a mixture of tin and lead. But when it was discovered that lead was poisonus, it changed to a mixture of mainly tin.
