Wikipedia info
(Wikipedia excerpt: “….Solder “S” is a fusible metal alloy used to create a permanent bond between metal workpieces. “S” is melted in order to adhere to and connect the pieces after cooling, which requires that an alloy suitable for use as “S” have a lower melting point than the pieces being joined. The “S” should also be resistant to oxidative and corrosive effects that would degrade the joint over time. “S” 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),[3] and is commonly used in electronics, plumbing, and sheet metal work. Alloys that melt between 180 and 190 °C (360 and 370 °F; 450 and 460 K) are the most commonly used. Soldering performed using alloys with a melting point above 450 °C (840 °F; 720 K) is called “hard “, “silver “, or brazing.  In specific proportions, some alloys are eutectic — that is, the alloy’s melting point is the lowest possible for a mixture of those components, and coincides with the freezing point. Non-eutectic alloys can have markedly different solidus and liquidus temperatures, as they have distinct liquid and solid transitions. Non-eutectic mixtures often exist as a paste ….”)
