True alloy is one of the eutectics, ie it has a sharp melting point (138ºC) and, like the majority of Bismuth based alloys, it expands on solidification, it is free flowing and its versatility makes it a unique tool in a great variety of industries. Its low melting point ensures easy and safe handling and under normal conditions it can be re-used almost indefinitely.
