Metals

1. Steel

   • Tough and resistant to traction
   • Structures in contructions, machines, tools etc.

2. Aluminium

   • It’s light and is a good electrical and thermal conductor.
   • We use it in high voltage electric cables, aeroplanes, cars, bikes

3. Titanium

   • It’s light, very hard and resistant.
   • We use it in the aerospace industry, architectural structures and medical prothesis.

4. Zinc

   • It’s fragile and not very hard.
   • We use it for cladding buildings, drainpipes, in the auto industry and for galvanising steel

5. Tin

   • Soft, malleable and resistant to oxidation.
   • We use it to make tin foil and tin cans

6. Lead

   • It’s soft, heavy and has a lot of plasticity.
   • We use it in batteries and accumulators, and in protection against nuclear radiation.

7. Cooper

   • It’s reddish and soft, and is a good electrical and thermal conductor.
   • We use it to make electric cables, phone cables, motor coils, pipes, boilers and radiators.

8. Brass

   • This is an alloy of copper and zinc. It’s very resistant to corrosion.
   • We use it in decorative items, cutlery, pipes, turbines and capacitors.

9. Bronze

   • This alloy of copper and tin is resistant to wear and corrosion.
   • We use it to make boat propellers, filters, bells, nuts and screws.
