NASA has been using aluminum for over 50 years. Today, it’s one of the first materials manufacturers in spacecraft and aircraft go to, for dozens of reasons. Aluminum, like any NASA-selected materials, have to be able to withstand the environment they are in. In space, exacerbated conditions include extreme stress, high pressure, and lower than average temperatures. Aluminum is a metal of choice because it accomplishes high marks on all these.

Did You Know that Even NASA Uses Aluminum for Construction – it’s true!

Aluminum makes up some of the main components of spacecrafts, as selected by NASA engineers. Aluminum thrives at overcoming the challenges of launch, landing, and low-earth orbits. There are 3 primary ways aluminum in NASA construction are used.

Temperature protection.

Thermal protection is so, so important. NASA has to use layers of components such as gold, aluminum, titanium, and nickel to establish a thermal blanket of protection on their satellites, space telescopes, and rockets, as well as anything else they have to send into space. These thermal, temperature-controlled blankets reflect external heat from the sun while also trapping internal heat on any sides facing away from the sun.

Radiation protection.

The sun transfers heat through – you guessed it – radiation. This heat is transferred to any equipment, astronauts, and anything else up there in space. If the surface temperatures of any object is not being adequately controlled, this begins exposing said object to the effects of dangerous radiation from the sun. For this reason, most NASA equipment – if not all – is wrapped in aluminum metal reflectors. These are made with silver, copper, and gold as well, helping equipment and astronauts maintain a consistent and comfortable temperature.

Spacecraft components.

Aluminum has high marks on strength, long-term durability and performance, and weight efficiency. NASA uses aluminum for these 3 reasons to produce a wide array of mechanical components, including control arms, aluminum wheels, steering knuckles, brake calipers, and automotive cross members. All these things would not be possible without NASA employing aluminum.

NASA’s very own aluminum alloy!

NASA has even gone on to create its own aluminum alloy which is now known as NASA-427. Improvements in strength is perhaps its most advantageous benefit. More strength means less aluminum is required which helps to minimize weight, also more cost-effective for less material, shortened processing times, and it still meets all corrosion resistance standards. NASA-427, a new, stronger aluminum has potential applications on aluminum wheels, control arms, steering knuckles, brake calipers, automotive cross members, and on differential carriers.

Why aluminum is a preferred metal.

Aluminum is used by so many industries in addition to spacecraft component design and manufacturing for the same reasons it’s used by NASA. It’s a readily abundant, highly reactive, can be readily combined with other metals which makes it so useful, and it’s a source of seemingly never-ending innovation.

Aluminum in NASA is one of their most important materials, used consistently to update and improve spacecraft technology as well as to assist in the design of completely new technologies. Aluminum has helped and will continue to help make spacecrafts more cost-effective, eco-friendly, and energy-efficient. In the decades to come, aluminum will likely continue to serve much purpose in manufacturing aircraft components and in allowing astronauts to travel the solar system in the most efficient way.
