The basic formula is defined in rather academic terms; Galinstan® is a trademarked, stabilised version.
In many applications (e.g. thermometers, contact materials), yes. In others (e.g. barometers), the higher surface tension is disadvantageous.
A eutectic is an alloy with a precisely defined composition ratio, in which the mixture has a minimum melting point. Galinstan® melts at −19 °C, even though its individual components have higher melting points.
