The Aluminum Use in the World

Aluminum alloy is used more and more widely in the world. Why?

The use of aluminum is to increase the sustainable use of energy. For example, aluminum’s light weight contributes to increased fuel efficiency in vehicles ranging from passenger cars to armored tanks. The metal’s 95 percent light-reflectivity contributes cooling efficiencies to “green” buildings and improves the energy production efficiency of solar cells. The aluminum industry is making continuous improvements in the environmental efficiency of producing aluminum through primary and secondary processes.

  • The industry leads the way to sustainability. Since the early 1990s, the aluminum industry has decreased greenhouse gas emissions from primary production by 37 percent and from secondary production by more than 50 percent.
  • Secondary production saves energy. Secondary production (aluminum produced from recycled material) saves more than 90 percent of the energy required to produce primary aluminum. Secondary and primary aluminum are chemically indistinguishable from one another.
  • Recycling is efficient and widespread. The metal is 100 percent recyclable without loss of the metal’s properties. Recycling is also widespread. According to a study by Delft University of Technology in 2012 , more than 90 percent of aluminum in buildings is recycled.
  • Inherent energy savings. The use of aluminum to make industrial products inherently brings sustainable results. As an example, structures built with aluminum exteriors naturally reflect light and remain cooler.
