As a part of the 3A group of chemical elements, Indium has similar properties to gallium, namely, it is very soft and ductile, and has a low melting point, making it a liquid in a wide range of temperatures. Its alloys can have custom tailored melting points making this metal useful in the construction of thermal fuses. Indium coatings are used to enhance lubrication in high-speed bearings and to produce mirrors with better reflectivity than aluminium, similar to silver but with better tarnish resistance.
