Compacted graphite iron (CGI), also known as vermicular graphite iron (GJV, VG, JV or GGV from the German: "Gusseisen mit Vermiculargraphit") especially in non-English speaking countries, is a metal which is gaining popularity in applications that require either greater strength, or lower weight than cast iron.
