Properties of Aluminum and Resulting End Uses

The properties of aluminum that contribute to its widespread use are:

• Aluminum is light; its density is only one-third that of steel.
  
• Aluminum is resistant to weather, common atmospheric gases, and a wide range of liquids.
  
• Aluminum can be used in contact with a wide range of foodstuffs.
  
• Aluminum has a high reflectivity and, as a result, is employed in a number of decorative applications.
  
• Aluminum alloys can equal or even exceed the strength of normal construction steel.
  
• Aluminum has high elasticity, which is an advantage in structures under shock loads.
  
• Aluminum keeps its toughness down to very low temperatures, without becoming brittle like carbon steels.
  
• Aluminum is easily worked and formed; it can be rolled to very thin gauges.
  
• Aluminum conducts electricity and heat nearly as well as copper.
