The melting point of solder depends on its composition and type. Solder is an easily fusible metallic material that melts when heated and solidifies on cooling. The typical melting point of general solder is in the range of 90 to 450 °C (190 to 840 °F; 360 to 720 K) . Soft solder, which is commonly used in electronics, plumbing, and sheet metal work, typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K) . Alloys that melt between 180 and 190 °C (360 and 370 °F; 450 and 460 K) are the most commonly used. For example, solder with a composition of 60% tin and 40% lead has a varying melting range but will begin turning into liquid at 361.4°F (183°C), then completely turn into liquid at 375.8°F (191°C) . The melting point of a silver solder is 1145 °F (618.3°C), while zinc/aluminum solder has a relatively lower melting point of 719.6°F (382°C) . The melting point of solder depends on its composition and type.
