Solder (/ˈsɒldə(r)/ or /ˈsəʊdə(r)/ or American /ˈsɒdər/) 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 what is most often thought of when solder or soldering are mentioned and it typically has a melting range of 90 to 450 °C (190 to 840 °F). It is commonly used in electronics and plumbing. Alloys that melt between 180 and 190 °C (360 and 370 °F) are the most commonly used. By definition, using alloys with melting point above 450 °C (840 °F) is called hard soldering, silver soldering or brazing. Soft solder can contain lead and/or flux but in many applications solder is now lead free. Perhaps the most common and most familiar form of solder is as a wire or rod, though plumbers often use bars of solder while jewelers often use solder in thin sheets which they cut into snippets. Solder can also come in a paste or as a preformed foil shaped to match the workpiece. The word solder comes from the Middle English word soudur, via Old French solduree and soulder, from the Latin solidare, meaning "to make solid".
