Solder (, ) is a fusible metal alloy used to join together metal workpieces and having a melting point below that of the workpiece(s).
Soft solder is typically thought of when solder or soldering is mentioned, with a typical melting range of . It is commonly used in electronics, plumbing, and assembly of sheet metal parts. Manual soldering uses a soldering iron or soldering gun. Alloys that melt between are the most commonly used. Soldering performed using alloys with a melting point above is called 'hard soldering', 'silver soldering', or brazing.
For certain proportions an alloy b...
