Application Note Cast Iron.pdf

For making Compacted graphite iron (CG) the same raw material is used as for mak-ing ductile iron. By carefully controlling the amount of magnesium added to the melt for nodulizing approx. 80% of graphite is formed as compacted graphite, the rest as nodules. The quality control of compacted iron is very important as the formation of graphite is critical.
