  • Topic 1.2 Metals
    • Ferrous metals contain ferrite (iron), almost all ferrous metals are magnetic and all rust due to their iron content.
      • An example of a ferrous metal is: steel.
        • Advantages of Steel: it is a lightweight material that can be easily formed into a range of shapes. Steel is ductile, malleable, it has good tensile strength and tough.
          • Disadvantages of steel:Steel rusts very easily.
    • Non Ferrous metals are the metals that contain no iron compounds therefore do not rust. These metals are perfect for jobs where they may come into contact with moisture.
      • Examples of Non Ferrous Metals are Aluminium and tin.
        • Advantages of Aluminium: is that it is lightweight, easily shaped, it doesn't rust and its is strong. It also conducts electricity well.
          • Disadvantages of Aluminium: Expensive
          • Aesthetics of Aluminium:
        • Advantages of tin is that it is malleable, ductile and resistant to corrosion.
          • Disadvantages of tin is that it is weak and soft.
  • Alloys are metals that are formed by mixing two or more metals to create a new metal which has improved properties.

  • The aesthetic of steel is that it is grey and soft.
    • The functional properties and uses of steel is  that it can be used for food and aerosol cans, nuts, bolts and car bodies.
