[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2016-0171298 filed on December 15, 2016, the entire contents of which are hereby incorporated by reference. technical field [0003] Exemplary embodiments of the present invention relate to an aluminum alloy for an insert ring, an aluminum insert ring using the aluminum alloy, and a piston manufacturing method using the aluminum insert ring. Background technique [0004] In a typical gasoline engine, combustion occurs by igniting a homogeneous fuel-air mixture with a spark plug before initiating combustion. In a typical diesel engine, however, self-ignition combustion occurs in such a way that only air is introduced into the chamber and compressed at a high compression ratio, and then fuel is injected into the chamber at high pressure. Specifically, in most diesel engines, a method is mainly used for combustion in which fuel injected by an injector...
