Aluminium Roofing

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

Copper Roofing

Copper as a Heat Exchanger

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

Bell Metal

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

Lead as a Roofing Material

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

Brass Components

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

Magnesium

Magnesium Wheel

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

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

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

Titanium heat-exchangers

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.

Nickel-based superalloys

Single-crystal blades

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, 10- 15%Sb,1.5-3.5% 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.
