The Uses of Metals: Physical and Chemical Properties

The video discusses how the uses of metals are linked to their physical and chemical properties. It covers general properties of metals like conductivity, malleability, and density, and highlights exceptions such as brittle iron and liquid mercury. The video focuses on aluminium, noting its low density, strength, and corrosion resistance, making it ideal for aircraft and food containers. Copper's conductivity and ductility are discussed, with a comparison to aluminium for overhead cables. The presentation concludes with a summary of metal uses.
