An iron alloy is a mixture of iron with other elements, which enhances its properties for various applications. Common alloying elements include carbon, manganese, and chromium. These additions improve strength, durability, and resistance to corrosion, making iron alloys suitable for construction, manufacturing, and automotive industries. One of the most well-known iron alloys is steel, which primarily consists of iron and carbon. Steel is widely used due to its versatility and ability to be shaped into different forms. Other examples of iron alloys include cast iron and stainless steel, each with unique characteristics tailored for specific uses.
