True. Solder is a metal alloy that is used to join two or more metal parts together by heating the solder and melting it onto the joint, where it solidifies and forms a strong bond between the metal parts.
Traditionally, solder has been made from an alloy of lead and tin in varying proportions, depending on the desired properties of the solder.
Lead and tin are both relatively soft metals, which makes them easy to melt and work with, and their combination in solder provides a good balance of strength, ductility, and workability.
However, lead is a toxic metal, and its use in solder has become increasingly restricted in many countries due to health and environmental concerns.
As a result, alternative solder alloys have been developed that either eliminate or reduce the amount of lead in the alloy, such as tin-silver-copper alloys and bismuth-tin alloys.
