Aluminum Alloys

The story of aluminum’s history of use in the U.S. now stretches over 100 years. The start was a modest one, however. Because of the complexities of refining aluminum from ore, aluminum was considered more rare and precious than gold or silver through most of the 19th century. A pure form of the metal was first successfully extracted from ore in 1825 by Danish chemist Hans-Christian. Techniques to produce aluminum in ways modestly cost-effective emerged in 1889. This lightweight, 100 percent-recyclable metal has since become a foundation of our country’s infrastructure. Used in packaging, automotive, energy, construction, transportation, energy, aerospace and defense applications, to name a few—aluminum’s impact is so profound that historians may one day look back on our times and declare this “The Age of Aluminum.”
