Modern airplanes like the Boeing 787 are often comprised of at least 50% composite materials. Consisting of reinforcing fibers mixed with a polymer matrix, they offer a superior strength-to-weight ratio. Airplanes, however, still contain other materials, such as aerospace-grade aluminum. Here are six facts about aerospace-grade aluminum.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">#1) Not the Same as Aluminum<\/h2>\n\n\n\n<p>Aerospace-grade aluminum isn&#8217;t the same as plain aluminum. It&#8217;s essentially a specialized alloy consisting of aluminum with other elements. Plain aluminum is susceptible to stress fatigue and oxidation. Therefore, other elements like&nbsp;copper, zinc, magnesium and lithium are added to it. The end result is aerospace-grade aluminum, which is typically stronger and more durable than plain aluminum.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">#2) Strong and Lightweight <\/h2>\n\n\n\n<p>Aerospace-grade aluminum is strong and lightweight. Plain aluminum is known for being relatively weak, with a tensile strength of around 13,000 pounds per square inch (PSI). Aerospace-grade aluminum, on the other hand, has a tensile strength of around 45,000 to 90,000 PSI &#8212; sometimes even higher. Even with its high tensile strength, aerospace-grade aluminum is lightweight, making it ideal for use in airplanes and other aircraft.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">#3) Available in Different Types<\/h2>\n\n\n\n<p>While they all consist of aluminum and alloying elements, not all aerospace-grade aluminum is the same. Common types of aerospace-grade aluminum include aluminum 7075, aluminum 7068 and aluminum 2024. Each type has a different composition of alloying elements, resulting in different physical characteristics. Aluminum 7068, for instance, has a very high tensile strength, whereas aluminum 2024 has a better strength-to-weight ratio.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">#4) Used For Many Aircraft Parts<\/h2>\n\n\n\n<p>Many aircraft parts are made of aerospace-grade aluminum. Fuselage skins, for instance, are often made of this strong and lightweight aluminum alloy. The wings are also regularly made of aerospace-grade aluminum. Even aircraft frames and landing gear systems are made of aerospace-grade aluminum.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">#5) Excellent Resistant to Corrosion<\/h2>\n\n\n\n<p>In addition to being strong and lightweight, aerospace-grade aluminum offers excellent resistance to corrosion. Aluminum itself develops a natural layer of oxide when exposed to oxygen, which helps to preserve and protect it from oxidative damage like corrosion. Aerospace-grade aluminum, though, contains other alloying elements to further enhance its resistance to corrosion.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">#6) Recyclable<\/h2>\n\n\n\n<p>Aerospace-grade aluminum is recyclable. When an airplane reaches the end of its usable life, it&#8217;s typically broken down for parts. Parts that can&#8217;t be reused or repurposed may be recycled, including those made of aerospace-grade aluminum. Recycling saves as much as 95% of the energy needed to produce new aluminum materials.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Composite materials have become increasingly common in the aerospace industry.
