Aluminum is everywhere—literally. The most abundant, naturally occurring metal in the earth’s crust, aluminum is an essential element of modern life. Virtually every person in the United States, and indeed most of the world, uses aluminum every single day.
The metal is so ubiquitous that many of us don’t even realize how often it touches our lives. In fact, people use more aluminum today than at any point in the 125-year history of the metal’s commercial production. Aluminum is so critical to modern mobility, increasing sustainability and the national economy that without it, many of the conveniences of today’s world would simply not exist.
Mobility
Innovative applications for aluminum are all around us. The car you drive to work most likely has an aluminum hood and other lightweight parts to drive fuel efficiency. Your house or office building likely uses aluminum windows and doors or maybe even a cool roof to improve insulation and decrease heating and cooling bills.
That airplane you fly in for summer vacation or that latest business trip would literally not be possible without lightweight aluminum as a key component. Increasingly, even the high-tech gadgets you use to keep in touch with friends and family make use of sleek, attractive aluminum casings.
Sustainability
Outside the day-to-day conveniences that aluminum provides, it is also the sustainable material of choice in many markets. As the United States and the rest of the world strive for a more fuel-efficient future, aluminum is a big part of the solution.
Lightweight, durable and infinitely recyclable, value-added aluminum products can lower energy costs and carbon emissions in dozens of applications. Coated aluminum roofs can reflect up to 95 percent of sunlight, dramatically increasing building energy efficiency.
Highly recycled and lightweight aluminum packaging can reduce shipping costs and carbon emissions for beverage makers. The Department of Energy’s Oak Ridge National Laboratory found that an aluminum-intensive vehicle can achieve up to a 32 percent reduction in total life cycle energy consumption. From light-weighting to recycling, the aluminum industry is a solution to the world’s energy needs.
Economy
Aluminum is an essential element to this country’s energy and manufacturing future.
The industry today supports 672,000 jobs and $152 billion in economic output in the United States—that’s nearly 1 percent of GDP. These high quality, advanced manufacturing jobs provide average compensation far exceeding the national average.
Demand for the metal is also moving in the right direction—up around 30 percent since 2009. And the industry is poised for even greater success as more and more companies turn to aluminum as a solution to modern manufacturing challenges—from Ford to Apple to the U.S. military.
Aluminum is truly the metal of modern life.
It’s lightweight—Aluminum weighs less by volume than most other metals. In fact, it is about one-third the weight of iron, steel, copper, or brass. This makes it easier to handle and less expensive to ship.
It’s strong—Aluminum profiles can be made as strong as needed for most applications. Cold-weather applications are particularly well-served by aluminum because, as temperatures fall, aluminum actually becomes stronger.
It’s non-corrosive—Aluminum does not rust. It’s protected by its own naturally occurring oxide film, a protection that can be further enhanced by anodizing or other finishing techniques.
It conducts heat—Based on weight and overall cost, aluminum conducts heat (and cold) better than other common metals. These factors make it ideal for applications requiring heat exchangers.
It’s non-sparking—Aluminum doesn’t emit sparks. This makes it a great choice in applications that involve explosive materials or that are used in highly flammable environments.
It conducts electricity—Bulk power transmissions generally take place via aluminum because, pound-for-pound, aluminum is twice as conductive as copper.
It’s nonmagnetic—Because aluminum does not acquire a magnetic charge, it’s useful for high-voltage applications, as well as for electronics, especially where magnetic fields come into play or where sensitive magnetic devices are employed.
It’s resilient—Aluminum combines strength with flexibility and can flex under loads or spring back from the shock of impact.
It’s reflective—Highly reflective aluminum can be used to shield products or areas from light, radio waves, or infrared radiation.
It’s non-combustible—Aluminum does not burn and, even at extremely high temperatures, it does not produce toxic fumes.
It’s recyclable—Aluminum retains a high scrap value. It can be recycled indefinitely without losing any of its superior characteristics.
It accepts finishes—Aluminum can be finished with a variety of common techniques, including liquid paint, powder coatings, anodizing, or electroplating.
It’s seamless—With aluminum, complex shapes can be realized in one-piece extruded sections without having to use mechanical joining methods. This makes the parts stronger and less likely to leak or loosen over time.
