How to use Fusible Alloys

From Indium Corporation

Fusible alloys are materials that melt at less then 300°F, well below the melting point of tin-lead eutectic solders and SAC alloys. Bismuth is the major component of many of these alloys and influences the melting point, as well as gives these materials the unique characteristic of expansion upon solidification. This expansion, which can continue for hours or even days after solidification, has proven to be a useful property in many processes.
