Solder is a fusible metal alloy used to create a permanent bond between metal workpieces.
The percentage of each metal varies, depending on the desired properties of solder.
Soft solder typically has a melting point range between 90 to 450 °C, and is commonly used in electronics, plumbing, and sheet metal work. Alloys that melt between 180 and 190 °C are the most commonly used. Soldering performed using alloys with a melting point above 450 °C is called "hard soldering", "silver soldering", or brazing.
The thermal conductivity of common solders ranges from 32 to 94 W/(m·K), and the density from 9.25 to 15.00 g/cm3.
Solder can be bought from all electronics stores and are also available in many hardware and home-improvement stores.
