Cast Iron

Definition

Cast iron is iron with a high carbon content, which cannot, because of the percentage of carbon, be classified as steel.

Purpose

Cast iron is used for its excellent castability, wear resistance, and compressive strength. It is commonly employed in manufacturing heavy-duty machinery, engine blocks, pipes, and cookware.

Examples of Use

1. Engine Blocks: Constructing durable and heat-resistant engine components.
2. Cookware: Making pots, pans, and other kitchen utensils that retain heat well.
3. Machinery Parts: Producing industrial machine components that require high strength and durability.

Related Terms

• Steel: An alloy of iron with a lower carbon content, known for its ductility and strength.
• Wrought Iron: Iron with a very low carbon content, known for its malleability.
• Alloy: A mixture of metals or a metal combined with one or more other elements.

Notes

While cast iron is brittle and can crack under impact, it excels in applications where strength, durability, and heat retention are needed. It requires proper care to prevent rusting, especially in cookware.
