  • 15. Other non-ferrous metals
    • Copper
    • Tin
    • Lead
    • Zinc
    • Titanium
    • Lithium
    • Nickel
    • Chromium
  • 16. Copper
    • Moderate strength in the pure state
    • Malleable and ductile
    • Very good electrical and thermal conductor
    • Good corrosion resistance
    • Alloys with Zinc to give brass
    • Alloys with Tin and others to make bronze
  • 17. Copper Roofing
  • 18. Copper as a Biocide
  • 19. Copper as a Heat Exchanger
  • 20. Tin
    • Soft and corrosion resistant.
    • Used to alloy with lead to make solder
    • Used to alloy with copper to produce bronzes, e.g. Bell metal
  • 21. Bell Metal
  • 22. Lead
    • High Density
    • Corrosion Resistant
    • Malleable, but not ductile
    • Very soft and weak
  • 23. Lead Applications
  • 24. Lead as a Roofing Material
  • 25. Zinc
    • No structural engineering uses in pure state
    • Used as sacrificial anodes to protect steel.
    • Used as an alloy with copper to produce
    • brass
    • Used to corrosion coat steel by:
      • Galvanising or
      • Plating
  • 26. Brass Components
  • 27. Magnesium
    • Light weight – S.G. of 1.7
    • Burns easily when being machined
    • Used with Aluminium to make lightweight alloys.
  • 28. Magnesium
  • 29. Magnesium Wheel
  • 30. Lithium
    • Very light, S.G. of 0.5!
    • Used to make alloys with Aluminium for aerospace applications.
    • Used in batteries for mobile phones etc.
  • 31. Titanium
    • Low density (S.G. of 4.5, as compared to steel at approx 8)
    • Similar strengths to steels
    • Highly corrosion resistant
    • Melts at 1670°C
    • Use restricted to <400 °C
  • 32. Titanium
    • Used in
    • Aerospace parts
    • Racing cars, motorcycles and bicycles
    • Pipework and heat exchangers in chemical plants and oil installations.
  • 33. Titanium heat-exchangers
  • 34. Nickel
    • Corrosion resistant – forms strong oxide layer.
    • Brittle in the pure state
    • Used in stainless steels
    • Alloyed with copper to produce cupronickels for coinage and Monel for corrosion-resistant valve parts.
    • Used in Nimonic and superalloys for aerospace engine parts.
  • 35. Nickel-based superalloys
  • 36. Single-crystal blades
  • 37. Chromium
    • Corrosion resistant – forms strong oxide layer.
    • Brittle in the pure state
    • Used in stainless steels
    • Used with Ni & Mo to produce strong steel alloys for bicycle and motorcycle frame tubes.
  • 38.
