Abstract

The present invention relates to cast iron, and more specifically relates to CGI (Compacted Graphite Iron) cast iron in which the amounts of carbon (C), silicon (Si), manganese (Mn), copper (Cu), tin (Sn) and magnesium (Mg) are controlled during production, thereby improving the castability and also giving a stable tensile strength and yield strength and giving an appropriate range of hardness, and also to a production method for the same.
