For example: The fact that the density of aluminium is only about 1/3 that of steel and copper means that aluminium has become one of the most used light metals in automotive designs within the transportation sector. Aluminium’s low density, combined with good thermal conductivity, is also exploited in the production of heat exchangers for the automotive industry. Not only the automotive industry benefits from the good properties of aluminium, but also the producers of refrigerators and stationary air condition systems.
As a comparison it can be noted that, on a weight basis, aluminium is almost twice as good a conductor as copper, a fact used especially in the aviation and automotive industries.
The high electrical conductivity has similarly led to frequent use of aluminium for special electrical purposes.
