Indium is a very soft, corrosion-resistant and nontoxic metal with a melting point of 314 degrees Fahrenheit. It is so soft that it can be cut with a knife and easily bent and crushed with the fingers. An alloy called "galinstan" melts at about 0 degrees Fahrenheit, and contains gallium, tin and indium. The metal and its compounds have many uses. It can be used as a lubricant and low-temperature solder. It is so soft that it can be used in wire form as a gasket, easily conforming to the connecting parts and sealing them. Indium oxide is used as a conductive substrate for LCD screens.
