Compacted graphite iron Wikipedia

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. R.D. Schelleng obtained a patent for the production of compacted graphite iron in 1965.

Cast Iron Types Metal Casting Resources

There are also differences in composition—cast iron contains 2–4% carbon and other alloys, and 1–3% of silicon, which improves the casting performance of the molten metal. Small amounts of manganese and some impurities like sulfur and phosphorous may also be present. Differences between wrought iron and cast iron can also be found in the details of stone structure and physical

Compacted and Spheroidal Graphite Irons: Experimental

Although Compacted Graphite Iron (CGI) was first observed in 1940s, an unstable foundry production precluded its use for high volume production until advanced process control technologies became available [1-3]. Nowadays CGI is used for complex shape applications such as cylinder heads and engine blocks. As the demand for higher torque, lower weight and, consequently, lower emissions continues

Compacted Graphite Iron an overview ScienceDirect

Compacted Graphite Iron. Compacted graphite iron is an emerging cylinder block material having a higher specific strength than conventional gray iron, and with improved fatigue strength and acoustic properties relative to aluminum, thereby allowing cast iron blocks of reduced thickness and mass to be constructed (Tholl 1996).
