| n. (substance) | 1. atomic number 26, fe, iron | a heavy ductile magnetic metallic element; is silver-white in pure form but readily rusts; used in construction and tools and armament; plays a role in the transport of oxygen by the blood. |
| ~ metal, metallic element | any of several chemical elements that are usually shiny solids that conduct heat or electricity and can be formed into sheets etc.. |
| ~ alpha iron | a magnetic allotrope of iron; stable below 906 degrees centigrade. |
| ~ beta iron | an allotrope of iron that is the same as alpha iron except that it is nonmagnetic; stable between 768 and 906 degrees centigrade. |
| ~ gamma iron | a nonmagnetic allotrope of iron that is the basis of austenite; stable between 906 and 1403 degrees centigrade. |
| ~ delta iron | an allotrope of iron that is stable between 1403 degrees centigrade and the melting point (= 1532 degrees). |
| ~ ingot iron | iron of high purity. |
| ~ cast iron | an alloy of iron containing so much carbon that it is brittle and so cannot be wrought but must be shaped by casting. |
| ~ wrought iron | iron having a low carbon content that is tough and malleable and so can be forged and welded. |
| ~ steel | an alloy of iron with small amounts of carbon; widely used in construction; mechanical properties can be varied over a wide range. |
| ~ galvanized iron | iron that is coated with zinc to protect it from rust. |
| ~ iron ore | an ore from which iron can be extracted. |
| ~ pig iron | crude iron tapped from a blast furnace. |
| ~ scrap iron | iron to be melted again and reworked. |
| ~ structural iron | iron that has been cast or worked in structural shapes. |
