Question

Solder is a mixture of tin and lead that is used to join metals. The
melting point of tin is 232°C. The melting point of lead is 328°C.
Solder melts at 183°C.

Why does solder have a lower melting point than either tin or
lead?


Suggest an advantage of the low melting point of solder.

Answer 2

Answer:

Alloys commonly used for electrical soldering are 60/40 Sn-Pb, which melts at 188 °C (370 °F), and 63/37 Sn-Pb used principally in electrical/electronic work. This mixture is a eutectic alloy of these metals, which: has the lowest melting point (183 °C or 361 °F) of all the tin-lead alloys.
