Indium

Indium is a rare silvery-white metal. It is a soft, malleable metal. Like tin, it also makes noise when it bends.

Indium has a very low melting point of just 156.5985 °C, almost only the alkali metals have a lower melting point. Liquid indium leaves a wetting on glass.

Indium has a rather low hardness, it is even possible to cut through indium with a knife.
