  • Metallic Issues
    • Recycling Metals
      • Saves Energy
      • Saves limited supplies of metal ores
      • reduces pollution from extracting metals
    • Using metals in Construction
      • Benifits
        • Aluminium alloys are resistant to corrosion
        • copper is a very good conductor of electricity making it really good for electrical wires
        • Steel is very strong for scrapfolding
        • Lead can be easily bent making it very good for steal joints on roofs
      • Drawbacks
        • Iron and steel rust very easily
        • metals are more expensive than other materials
        • the exploitation of metals causes pollution and uses up the earth's limited resources
