The metals used in the aircraft manufacturing industry include steel, aluminium, titanium and their alloys. Aluminium alloys are characterised by having lower density values compared to steel alloys (around one third), with good corrosion resistance properties.

Aluminum is ideal for aircraft manufacture because it’s lightweight and strong. Aluminum is roughly a third the weight of steel, allowing an aircraft to carry more weight and or become more fuel efficient. Furthermore, aluminum’s high resistance to corrosion ensures the safety of the aircraft and its passengers.

Answer: Because when oxygen in air reacts with aluminum it forms aluminum oxide which acts as protective sheath and prevents corrosion. Answer: Iron and steel rust when they come into contact with water and oxygen.

Aluminum was used as the primary propellant for the space shuttle’s solid rocket booster motor because it has a high volumetric energy density and is difficult to ignite accidentally.

NASA uses a few layers of gold, titanium, nickel and aluminum to for a thermal blanket of protection around their satellites, space telescopes, and rockets, for protection from the vacuum of space.

Another material that often used in space is Aluminum as it is light in weight. Aluminum alloys are often strong and lightweight enough to be functional in space structures and satellites.

There are a wide variety of materials used for either, but satelites are usually made to be etremely light weight, and use materials such as titanium and alluminum. Addidtionally, they’ll use composites and alloys, such as nickel-cadmium or aluminum-beryllium.

Types of satellites

• Navigation satellites. The GPS (global positioning system) is made up of 24 satellites that orbit at an altitude of 20,000 km above the surface of the Earth.
• Communication satellites.
• Weather satellites.
• Earth observation satellites.
• Astronomical satellites.
• International Space Station (ISS)
