Eutectic Research. No. 1. The Alloys of Lead and Tin
The eutectic of the lead-tin series was chosen as a suitable example for early study partly because the alloys of this series are very easily prepared and manipulated, but principally because this series has hitherto been regarded as the typical example of the simplest class of binary alloys,

EUTECTICS - A Practical Guide to Phase Diagrams
The eutectic line is a horizontal line drawn between two one-phase fields a the eutectic temperature. The eutectic point is the exact temperature and composition at which the liquid phase solidifies into two seperate phases at a single temperature. The eutectic point in the Pb-Sn phase diagram is at 185 degrees celcius and approximately 75 at% tin.

Phase Diagram for Lead/Tin Eutectic Alloy. Phase Diagrams combine the information from the Cooling Curves of mixtures of metals with metals and with other elements to create a chart which is used to show the behaviours of different Alloy compositions as they change phases between Solid to Liquid states.

Solder – Tin – Lead Eutectic Alloy | nuclear-power.com
Solder – Tin – Lead Eutectic Alloy. Soldering is a technique for joining metals using a filler metal alloy that has a melting temperature less than about 425°C (800°F). Because of this lower temperature and different alloys used as fillers, the metallurgical reaction between filler and work piece is minimal, resulting in a weaker joint.

solid-liquid phase diagrams: tin and lead
60% tin and 40% lead. This is close to the eutectic composition (62% tin and 38% lead), giving a low melting point. It will also melt and freeze cleanly over a very limited temperature range. This is useful for electrical work. 50% tin and 50% lead. This will melt and freeze over a wider range of temperatures.

Lead - Melting Points of Binary Eutectic Alloys
The melting point of an alloy of two (binary) or more metals depends on the relative proportions of the ingredients. an eutectic mixture is the mixture where the melting point is as low as possible. Binary eutectic Lead - Pb - alloys, with composition and melting points are indicated below: Alloy Component. Weight of Alloy Component.

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.Lead mitigates the formation of tin whiskers, though the precise mechanism for this is unknown. Today, many techniques are used to mitigate the problem, including changes to ...

Attempts to prepare pure eutectic alloys of known constitution led to the discovery of discrepancies between the authors' experiments and the data on lead-tin alloys published by Roberts-Austen. A complete redetermination of the equilibria of the lead-tin system was therefore undertaken, by both pyrometric and microscopical methods.

Tin - Wikipedia
Tin with lead forms a eutectic mixture at the weight proportion of 61.9% tin and 38.1% lead (the atomic proportion: 73.9% tin and 26.1% lead), with melting temperature of 183 °C (361.4 °F). Such solders are primarily used for joining pipes or electric circuits.
