[2] It is a eutectic alloy of bismuth, indium, and tin, with the following mass fractions: 32.5% Bi, 51% In, 16.5% Sn.
[3] When prepared, Field's metal can be melted in hot water.
[4] Because it includes neither lead nor cadmium, it is much less toxic than Wood's metal.
[5] This alloy has been investigated as a possible liquid metal coolant in advanced nuclear power system designs.
[7][8] Although it is much less dangerous to use than other commonly melted metals, such as lead or aluminium, contact with Field's metal in the liquid state can cause third-degree burns.
