Ferrous & non-ferrous metals.

Cards (11)

  • Ferrous metals:
    Contain iron and are magnetic due to iron content. They are prone to rust and require a protective finish to prevent corrosion. Malleability and hardness depends on carbon content- the more carbon the harder and less malleable the steel becomes.
  • Cast iron:
    -Brittle if thin
    -Can be cast in a mould
    -Strong compressive strength
    -Good electrical and thermal conductivity
    -Poor resistance to corrosion.
    -Used for gates, manhole covers, drains and vices.
  • High carbon steel:
    -It's hard and brittle
    -Less malleable than mild steel.
    -Good electrical and thermal conductor.
    -Uses include tools, screwdrivers, and chisels.
  • Low carbon steel or mild steel:
    -Ductile and tough.
    -Easy to shape, braze and weld.
    -Good conductor of heat and electricity.
    -Corrodes easily.
    -Used as nuts and bolts, screws, bicycle frames and car parts.
  • Stainless steel:
    -It's a ferrous alloy. shiny silver when polished.
    -Hard and tough.
    -Good resistance to stains and corrosion.
    -Shiny silver when polished.
    -Used extensively in kitchen sinks, cutlery and hospital equipment.
    -Stainless steel is also used in architecture, aerospace and general transport.

  • Non-ferrous metals:
    They don't contain iron, aren't magnetic and don't rust.
  • Aluminium:
    -It's lightweight, malleable and strong.
    -Good conductor of heat and electricity.
    -Used in drinks cans, cycle frames and saucepans.
  • Copper:
    -Very malleable and an excellent conductor of electricity and heat – perfect for plumbing and central heating applications.
    -It is orange/brown when polished, but will oxidise green.
  • Silver:
    -Precious metal used in jewellery.
    -It's soft and malleable when hot,
    -Highly corrosion-resistant and a good conductor.
