The use of aluminum in automotive applications is expanding

The use of aluminum in automotive applications is expanding. Aluminum offers a lowerweight alternative to steel, potentially increasing the efficiency of vehicles. Efficiency gains can be used to lower the amount of energy needed for transportation, reducing the emissions while improving the energy security of the country. However, the application of aluminum in vehicles has been largely in select components, most notably as cast aluminum in the engine, transmission, and wheels. These areas still have large opportunities for penetration and other areas offer the potential for growth. Together, these opportunities could significantly expand the amount of aluminum used in vehicles.
