    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.

  • Solder Wikipedia

    Tinlead (SnPb) 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 solders tensile and shear strengths.Historically, lead has been widely believed to mitigate the formation of tin whiskers, though the precise mechanism for this is unknown.

    The words eutectic solder describe a solder alloy that melts and freezes at one single temperature. A good example of this is Tin 63% / Lead 37% solder which melts and freezes at 183 °C. This melting point is much lower than the melting points of either pure metal which are 232 °C (tin) and 327 °C (lead).

  • What Is Eutectic Solder? Reference

    Eutectic solder is a solder made of 37 percent lead and 63 percent tin and is also called 63/37 solder. Eutectic solder melts at a single temperature, which makes it preferable to noneutectic solder. Solder is a fusible metal alloy frequently used in plumbing, electronics and jewelry to join together metal pieces.

    PROPERTIES OF SOLDERS Farnell element14

    Multicore 96S alloy is the pure tin/silver eutectic alloy like pure tin, it is bright, hardly tarnishes, is leadfree and nontoxic, but unlike pure tin it is relatively strong. It has higher electrical conductivity than other soft solders and a melting point approximately 40°C higher than either 60/40, 63/37 or LMP alloys. For
