Metals are common elements found everywhere around us. Their weight and colour make them easy to recognise. They are good conductors of heat and electric current and their shine, pliability and flexibility is caused by their metallic bonds. This film is about the special characteristics of metals. You will find out that you extract metals from minerals in the Earth’s crust, that iron and steel are used in everything from tools to buildings, and that alloys are metals mixed with other substances. You will also find out that aluminium, magnesium and titanium are lightweight and reusable metals, but that the production of them can be energy-intensive and harmful for the environment. Finally the film shows you how to reuse metals to save both natural resources and energy.
