The primary difference in production between wrought iron and cast iron is that cast iron is not worked with hammers and tools. There are also differences in composition— Cast iron, an alloy of iron that contains 2 to 4 percent carbon, along with varying amounts of silicon and manganese and traces of impurities such as sulfur and phosphorus. It is made by reducing iron ore in a blast furnace.
COMPOSITION
All cast irons contain more than 2% C.
Cast iron is the alloy of carbon with 1.7 to 4.5%
Carbon and 0.5 to 3% silicon.
But in some alloy it has Manganese 0.5 to
1.0%, Phosphorous 0.1 to 0.9 %, & Sulphur
0.07 to 0.10%.
A few common mechanical properties for cast iron include: Hardness – material’s resistance to abrasion and indentation. Toughness – material’s ability to absorb energy.
Ductility – material’s ability to deform without fracture.
