What are the Material Properties vs. Casting Processes?

Material properties come from the makeup of the materials present. Some of the materials are added to the iron for strength while others are added to improve castability (affecting melting temperatures, etc.). 

The properties of all metals are also influenced by the way they solidify during cooling. If you change the cooling process, you automatically change the structure of the metal in its final state. How the cast part cools can be affected by how the metal is introduced into the mold, the pouring temperature, and the process and speed of cooling. One of the difficulties in making a quality casting is to account for the way a part will cool in different parts of the mold, accounting for both thick and thin areas of the mold.

What is the Composition of Gray Cast Iron?

Just like all cast iron parts, the primary component of Grey Iron is going to be the iron (no surprise there, right?).  Just like most other cast irons, it also has 2.5–4.0% carbon and 1–3% silicon.  If you look at Chart 2 you will notice that the composition of the iron is very close to other common cast parts, but with a little more phosphorus.
