iron alloys

Iron alloys are metals made by combining iron with other elements—most commonly carbon, but also chromium, nickel, manganese, and others.

Steel is the most familiar iron alloy, distinguished from pure iron by its carbon content.

Different alloy compositions yield different properties: stainless steel resists corrosion, cast iron handles high heat, tool steel maintains a sharp edge.
