A few important eutectics have an impact on ordinary life. Ordinary solder is a eutectic of tin and lead (63% and 37%, respectively) that melts at 183 C, whereas the melting points of tin and lead are 232 C and 327 C. Wood s …
Webtemperature than eutectic tin-lead solder’s (Sn63Pb37 or Sn63) 183°C, yet it is high enough for most soldering applications. In addition, its mechanical properties are similar to Sn63, but contain no lead. The alloy is near eutectic at its 137-139°C. Although a reflow temperature of 20-40oC above
