Iron vs. Cast Iron: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Updated on November 28, 2023
Iron is a chemical element, strong and malleable, while cast iron is an alloy of iron and carbon, known for its durability and brittleness.

Key Differences

Iron is a pure element in the periodic table, known for its strength and malleability, used in various forms in construction and manufacturing. Cast iron, on the other hand, is an alloy primarily made of iron and carbon, characterized by its excellent durability but also its brittleness.
