Field’s Metal (Smart Material)

This remarkable alloy melts at just 61°C, but does not contain lead or cadmium. It is relatively hard and extremely tough. It is used, for example, to fill small tubes for bending without crushing, castings for models and jewellery, and for making precision moulds. Fields metal makes a fantastic demonstration of how several constituents, each with a much higher melting point, can be combined to produce a useable alloy.

Demonstration use is recommended – Indium is a potentially toxic material if ingested. Before using a risk assessment should be carried out.
