Gray Iron, which grows by both graphitization and oxidation, exhibits higher growth rates than Ductile Iron. Table 3.1 compares the oxidation of different Ductile Irons and Gray Iron. Unalloyed Ductile Iron exhibits one-half the weight gain shown by Gray Iron.
Sep 07, 1990 ABSTRACT Gray iron is the most versatile of all foundry metals. The high carbon content is responsible for ease of melting and casting in the foundry and for ease of machining in subsequent manufacturing. The low degree or absence of shrinkage and high fluidity provide maximum freedom of design for the engineer.

Casting is the process of pouring the iron into a mold thus giving it a shape. Molds and pouring methods divide this process up. Molds can be made as expendable molds sand or non-expendable molds metal. Pouring can happen via gravity, low-pressure or vacuum. Controlling the pouring process becomes more important the more intricate the mold is.
