• They can conduct electricity as they have delocalized electrons.

• They can conduct heat by conduction.

• They are malleable - hammered or pressed into shape without breaking.

• They are ductile - able to be drawn out into a thin wire.

• They have a high melting point and boiling point.

• They have high density.

• They are all solid in R.T(except mercury which is liquid in R.T).

1. Aluminum

   • Manufacture of Aircraft/Cars (Low density)

   • Food Containers (Resistant to corrosion)

   • Overhead electrical cable (Good conductor of electricity/ductile)

2. Zinc

   • Galvanizes Iron = coats it to stop it from rusting (protective coating)

   • Alloys – brass/bronze

   • Batteries

   • Sacrificial Protection

3. Copper

   • Electrical Wiring (Good conductor of electricity/Ductile)

• Alloys are useful because they are harder and stronger/useful than pure metal; they can also resist rusting with air and water.

• They can conduct electricity as they are still metals.

• All alloys are not corrosive.
