1) coz it transmits heat energy very quickly
2) It is light in weight
3) expansion has nothing to do with the efficiency of the piston.
4) read the carnot's cycle, for more information.

Because its cheap, strong and if the engine block is made of the same aluminum alloy, it will expand at the same rate as the pistons.
