- Transition metals are the large block of metallic elements in the centre of the periodic table, many of which have similar properties.
- They are very good conductors of electricity and energy, they are strong but cam be bent into shapes with a hammer.
- Copper is a useful transition metal as it can be bent but is hard enough to be used as water tanks/pipes.

- Bronze was the first alloy made by humans by mixing copper with tin.
- It is used to make ships propellers because of how tough it is and its resistance to corrosion.
- Brass is made by alloying copper with zinc and it is harder than copper but workable.

- Aluminium has a low density for a metal and can be alloyed with a wide range of other elements.
- Some aluminium alloys are used to build aircrafts while others are used on military tanks.
