Metals, alloys and their use
Man uses metals still much today because of their valuable properties. The
main advantage of metals is their strength and toughness.
Plastics are lighter and more corrosion-resistant, but they are not usually as
strong as metals. Another problem with plastics is what to do with them after use.
Metals can be recycled but plastics can only be burned.
Not all metals are strong. Cooper and aluminium are metals, but if they are
mixed together, the result is an alloy called aluminium bronze which is much
stronger than either pure cooper or pure aluminium.
Alloying is an important method of obtaining required properties such as
strength, toughness, resistance to wear, magnetic properties, high electrical
resistance or corrosion resistance.
The properties of all metals can be further improved by use of heat
treatment. Heat treatment is a number of different procedures in which the
properties of metals and alloy to a selected temperature below its melting point and
then cooling it at a certain rate to obtain those properties which are required. For
example, hardening is used to make metals harder. Tempering makes them softer
and less brittle. Annealing is carried out to make a metal soft so that it can be
machined more easily. In this way, metallic materials can be produced to meet
every kind of engineering specification and requirement.
