17. Copper Roofing

18. Copper as a Heat Exchanger

19. Tin
Atomic number 50. Soft and corrosion resistant. Used to alloy with lead to make solder Used to alloy with copper to produce bronzes, e.g. Bell metal Used as coating for steel and sheet iron

20. Bell Metal

21. Lead Latin plumbum (Pb), atomic number 82. High Density
Corrosion Resistant
Malleable, but not ductile
Very soft and weak

22. Lead as a Roofing Material

23. Zinc Atomic number 30. 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

24. Brass Components

25. Magnesium Light weight – S.G. of 1.7 Burns easily when being machined
Used with Aluminium to make lightweight alloys.

26. Magnesium

27. Magnesium Wheel

28. Lithium Very light, S.G. of 0.5!
Used to make alloys with Aluminium for aerospace applications.
Used in batteries for mobile phones etc.

29. 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

30. Titanium Used in Aerospace parts Racing cars, motorcycles and bicycles
Pipework and heat exchangers in chemical plants and oil installations.

31. Titanium heat-exchangers

32. 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.

33. Nickel-based superalloys

34. Single-crystal blades

35. General Characteristics of White Cast Irons
There are also called as low- melting bearing alloys.lead based or tin based babbits containing antimony are most popular form this group.
Lead based : 1-10%Sn, %Sb, % Cu,1-1.7% Cd,1.0% As and balance Pb.
Tin based : upto 10%Pb, 5- 12%Sb,3-5%Cu,0.1%As.
