Engineering materials:
Almost every substance known to man has found its way into the engineering workshop at some time or other. The most convenient way to study the properties and uses of engineering materials is to classify them into ‘families’ as shown in figure below:
1. Metals
1.1 Ferrous metals
These are metals and alloys containing a high proportion of the element iron. They are the strongest materials available and are used for applications where high
strength is required at relatively low cost and where weight is not of primary importance.
As an example of ferrous metals such as : bridge building, the structure of large buildings, railway lines, locomotives and rolling stock and the bodies and highly stressed engine parts of
road vehicles.
1.2 Non – ferrous metals
These materials refer to the remaining metals known to mankind.
The pure metals are rarely used as structural materials as they lack mechanical strength
They are used where their special properties such as corrosion resistance, electrical conductivity and thermal conductivity are required. Copper and aluminum are used as electrical conductors and, together with sheet zinc and sheet lead, are use as roofing
materials.
