1. An expandable eutectic alloy based downhole tool, said tool comprising:
a tubular body configured to be expanded when an expanding tool is run through the inside thereof;
one or more eutectic elements provided on the outside of the tubular body, wherein each eutectic alloy element only extends partially around a circumference of the outside of the tubular body;
wherein said one or more eutectic alloy elements are arranged around the circumference of the tubular body so as to form a plurality of alloy rings that encircle the tubular body; and
wherein each alloy ring is interrupted by one or more gaps and said gaps in one alloy ring are not aligned with the gaps in an adjacent alloy ring.
