Properties of Metals
- Different metals have different properties and this will influence how they are used
- For example, aluminium has a low density, is a good conductor and is strong, so makes it ideal to be used as overhead power cables
Properties and uses of common metals
| Metal | Property | Use |
| Steel | Hard and strong | Buildings, reinforced concrete, cars, tools |
| Aluminium |
Strong Low density Good conductor of heat and electricity, Resistant to corrosion |
Aeroplane parts, cans, window frames, foils, overhead power cables |
| Copper |
Very good conductor of heat and Malleable and ductile Attractive colour and lustre |
Wiring, pipes, motors |
| Titanium |
Hard and strong Low density Resistant to corrosion High melting point |
Medical industry (surgical instruments, joint replacements), spacecraft, sports equipment |
Reinforced concrete block with steel rods
Steel rods are used to reinforce concrete to increase strength in buildings
Examiner Tip
Make sure you can explain why a substance is used for a particular use.
For example, copper is used in electrical wiring because it is a good conductor of electricity.
