- Grey iron is the most common type. That is why people use “cast iron” and “grey iron” terms interchangeably. Grey iron is widely preferred in engineering applications requiring no high strength or no ductility. Also, it can be used in sliding surface applications because of its unique strength.
- Ductile iron is also known as ductile cast iron, nodular cast iron, is a type of graphite-rich cast iron. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its nodular graphite inclusions.

- Composite material is a combination of two materials with different physical and chemical properties. When they are combined they create a material which is specialized to do a certain job, for instance to become stronger, lighter or resistant to electricity. They can also improve strength and stiffness.
