Metals - Key Words
| Alloy | A substance formed by the combination of two or more elements one of which must be a metal. Examples are steel, brass and bronze. |
| Aluminium | Transition element, very useful as it is both light, resistant to corrosion and strong. Most useful when alloyed. |
| Blast Furnace | Machine used for converting iron ore into iron |
| Brittle | |
| Carbon | Very useful non metal. Small amounts of carbon are mixed with iron to make the alloy steel. |
| Coke | Form of carbon used in a blast furnace to reduce iron ore |
| Dense | |
| Displacement reaction | A reaction where a more reactive element takes the place of a less reactive one in a compound |
| Ductile | |
| Electrolysis | When an electric current flows through a solution causing a chemical reaction |
| Hard | |
| Iron | Very useful transition element, particularly when alloyed to form steel |
| Limestone | A rock mostly made of calcium carbonate. It has many uses. It is used in the production of iron in a blast furnace. |
| Malleable | |
| Ore | |
| Reactivity | How readily an element takes part in a chemical reaction. Sodium is a very reactive metal. Gold is very unreactive. |
| Shape Memory Alloy | This metal returns to its original shape after being bent. Some spectacle frames are made from nitinol, a shape memory alloy. |
| Slag | A waste product from the production of iron in a blast furnace. |
| Steel | A very useful alloy |
| Strong | |
| Transition Element | |
