• J&F Rosin Core 63/37 Leaded Solder is ideal for electronics soldering.  The solder is comprised of a eutectic ratio of 63% tin to 37% lead, meaning it has the lowest melting point of any other mixture of tin lead solder, and a lower melting point than either of the two parts by themselves.  This is especially beneficial when soldering electronics circuitry which can be damaged by exposure to high temperatures.
• True melting point, rather than a range
