Characteristics of Metals

Metals have different characteristics and these characteristics are called properties. Selecting a metal which is to be used in a metal product an engineer must know about various metals and their mechanical properties. There are some characteristics common to all metals. We find, for example, metals are good conductors of electricity and heat, that is why copper and aluminium are widely used for cables. There are some mechanical properties of metals which determine their usefulness in the industries.

They are the following: strength (that is, the ability to carry a load); elasticit (i.e. the ability to deform under load and return to the original shape when the load is removed) and many others.

The mechanical properties of metals must be taken into consideration when selecting the material a part is made of.
