The Strength of Aluminum

If you’re like many people, when you hear the word “aluminum”, you think of everyday convenience items that, while

incredibly useful, don’t exactly convey a high-strength image. And it’s true – aluminum is a highly versatile metal –

meaning it can be processed to be thin, lightweight, bendable and even crushable by human hands.

What’s less well-understood is that aluminum can also be some of the toughest stuff on earth. Often, the metal is used

in applications where high-strength and durability are the most important considerations – from cars and trucks to building

material to military vehicles. You likely trust aluminum to keep you safe and secure dozens of times a day without even

knowing it.

Take-Away Facts

The Key to Auto Safety: Automakers are increasingly turning to aluminum as part of the multi-material mix to increase

vehicle fuel efficiency while maintaining strength and safety. Every aluminum-intensive vehicle ever crash tested by the

National Highway Traffic Safety Administration has earned a 5-star safety rating.

High-Strength Aluminum is Everywhere: High-strength aluminum alloys are used in hundreds of everyday applications where

strength and durability are essential – from planes to trains, buses to trucks – even some of the world’s tallest

skyscrapers.

Extreme Applications: Aluminum is also used by the U.S. military, NASA and others to build vehicles and structures

capable of thriving in some of the harshest conditions imaginable.

The Chemistry of Strength: By adding elements like silicon, magnesium and lithium to pure aluminum and through special

processing techniques, aluminum can be engineered to be as strong if not stronger than some steel.

Aluminum is about one-third the weight of steel, meaning parts can be made thicker and stronger while still reducing

weight in vehicles and other applications. Depending on the alloy and processing technique used, pound for pound aluminum can

be forged to be just as strong if not stronger than some steel.Aluminum is already the

second-most-used material by automakers, so your car or truck likely has a lot of aluminum in it right now, protecting you

from hazards on the road. Engineers know how to work with aluminum to make parts that perform as well or better than steel

parts – all while reducing vehicle weight. Aluminum is highly effective at absorbing crash energy, protecting passengers in

the event of an accident. And lighter aluminum vehicles improve performance. Better handling and shorter stopping distances

help drivers avoid accidents to begin with.

Aluminum is used for window frames and curtain wall in some of the world’s tallest skyscrapers – maybe even the office

building you’re sitting in right now. This versatile metal is used to make planes, trains, buses, trucks – even ocean

liners!

In short, every day, people around the world trust the strength of aluminum – whether they know it or not.

In addition to “everyday” applications, aluminum’s strength and durability is also trusted for some of the most

extreme uses imaginable. Designers know that high-strength aluminum alloys can handle some of the harshest conditions on

earth – and beyond.

U.S. Army: The U.S. Army has trusted aluminum for decades to help protect our troops. The high-strength, crash-absorbent

metal is used in the Humvee (HMMWV), HEMTT and Bradley Fighting Vehicle to reduce weight, resist rust and be reliab
