Fusible Alloys include a group of binary, ternary, quaternary, and quinary alloys containing bismuth, lead, tin, cadmium and indium. The term fusible alloy refers to any of the more than 100 white-metal alloys that melt at relatively low temperatures. 

Fusible alloys are materials that melt at less than 300F, well below the melting point of Tin-lead eutectic solders. The major component of fusible alloys is bismuth. Besides producing low melting point, bismuth also gives these materials the unique characteristic of  expanding on freezing. This expansion, which can continue for hours or even days after freezing, has proven to be a useful property in many processes.

Fusible Alloys are classified as either eutectic or non-eutectic. In eutectic alloys, the melting point coincides with the freezing point. Non-eutectic alloys exhibit a range between the melting and freezing point in which the material is "mushy" or "pasty".

Fusible Alloys are used for lens blocking and tube bending, for anchoring chicks and fixtures and for mounting thin sections such as gas turbine blades for machining. The eutectic fusible alloys, which can be tailored to give s specific melting point, find applications in
temperature control devices and in fire protection devices.
