What Makes Aluminum So Sustainable?

Aluminum is one of the most-used metals in the world. This durable but lightweight metal is made from bauxite and has a variety of applications in transportation, construction, and packaging. The best part is that it is completely recyclable. In fact, three-quarters of all aluminum created in history is still in use today. So, why is aluminum so sustainable?


Because it has a lower atomic weight than other metals, aluminum has a low density. Its density is between 2.6 and 2.8 grams per cubic centimeter. Aluminum has a density of around one-third that of steel, which is why it is often known as a light metal.

Resistant to Corrosion

One of the key reasons for aluminum’s exceptional corrosion resistance is this oxide layer. When left untreated, aluminum corrosion resistance is excellent in most conditions. This is due to the fact that aluminum generates a thin but efficient oxide coating on its surface that prevents further oxidation. Aluminum oxide is impermeable and sticks strongly to the parent metal, unlike the oxide coatings on many other metals. The oxide layer of aluminum repairs itself promptly if it is mechanically damaged.


Aluminum has the potential to become one of the toughest metals on the planet. Aluminum alloys are utilized in a variety of applications that require strength and durability. High-strength aluminum is used in the construction of planes and automobiles as well as some of the world’s tallest buildings. The strength of aluminum is increased by adding components like silicon, magnesium, and lithium to the pure metal. This method can produce a metal that is as robust as, if not more so than, steel.


Aluminum metal used to be more valuable than gold when it was first discovered. Although aluminum is now the most abundant metal on the planet, it is still a costly metal. This is due to the significant quantity of electricity consumed in the extraction process. However, when compared to other metals for production, the price of aluminum might be considered as reasonable due to its many favorable features.

The metal fabrication industry is expected to add 12,000 jobs over the next decade, according to the U.S. Bureau of Labor Statistics. That means that more and more workers will be using metals like aluminum. Thankfully, aluminum is also called a green metal because of its sustainability. It is lightweight, corrosion-resistant, durable, and affordable, among other reasons. Get in touch with us today to learn more about aluminum.
