Details

Named after its inventor, Simon Quellen Field, Field's metal is Eutectic at 144 F, 62 C. Field's metal is expensive due to the price of indium, which makes up over half its mass. However, as it contains neither lead nor cadmium, it is a less toxic alternative to Wood's metal. It is used for die casting and rapid prototyping.
