Solder - Wikipedia
Solder used in making electrical connections also needs to have favorable electrical characteristics. Soft solder typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K), and is commonly used in electronics, plumbing, and sheet metal work.
Solder alloys - Wikipedia
Solder alloys are metallic materials that are used to connect metal workpieces. This is achieved by melting the alloy and then cooling it down. The choice of specific alloy depends on its melting point, stone reactivity, mechanical properties, toxicity, and other properties.

Tin-Lead Solders - eFunda
Tin, lead and their alloys, due to their low melting temperatures and wide availability, are the most commonly used solder materials. In fact, lead has been used as a soldering metal for water pipes (also made of lead) even in Roman times, hence the scientific name for lead, Plumbum.

What is Solder | Electronics Notes
What is solder? Traditional solder that used to be used for soldering in the electronics industry used to be a mixture of tin and lead. Different types of solder are used for different purposes. Solder is of course used in plumbing. The type of solder used for electronics usually contains 60% tin and 40% lead. This is often known as "60/40" solder.
Choosing the Right Solder Alloy and Flux — Omnia …
Choosing the Right Solder. Solder alloy composition is important when choosing the right solder for the metal to metal joint. Choosing an alloy with similar conductive and strength material properties as the base metal will reduce the need to compensate for a weak joint.
