| Ferrous Metal | Metals whose chief ingredient is iron |
| Non-Ferrous Metal | Metals which have no iron and made up of single elements |
| Ferrous Alloys | Metal made up largely of ferrous materials but have other elements in sufficient quantities to change the ferrous characteristics |
| Non-Ferrous Alloys | Metals that are made up of two or more non-ferrous elements |
| Toughness | The resistance to fracture after permanent deformation. |
| Tempering | Obtaining the desired hardness and toughness in metal |
| Melting point | The point at which a metal starts to change from solid to liquid. |
| Lattice | The fundamental geometric structure of the crystals |
| Iron | A crystalline metallic element. Symbol Fe |
| Heat | A type of energy |
| Hardness | The ability of a metal to resist denting |
| Hardening | Making steel harder |
| Grains | Most similar crystals closely packed together in standard symmetric pattern |
| Fusin | The mixing of molten metals. |
| Carbon | Nonmetal mixed with iron |
| Casting | Pouring metal into a mold, so when it cools it is in a shape |
| Ferrite | Elemental iron which is usually very soft |
| Adhesion | Sticking together of two unlike metals involving a mechanical bond |
| Alloy | A mixture of two or more metals or metals and one or more non-metals |
