The aerospace industry is constantly pushing the boundaries of innovation and technology, and the materials used play a crucial role in this progress. 

The aerospace business is always on the hunt for emerging technologies that cut costs, improve output and enable advancements. Aluminum alloys have proven to be an essential component in the development of lighter, stronger, and more efficient aircraft. 

This article will dive into how aluminum is important for the aerospace industry and check out the latest breakthroughs and advancements. Read on to learn more.

What Aluminum Alloys Are Used In Aerospace?

Aerospace-grade alloys offered by aluminum powder suppliers include 2024, 7075, 6061-T6, and 7050. These alloys fall into the 2xxx, 6xxx, and 7xxx series.

The 2xxx series, also known as the aluminum-copper alloys, are known for their high strength and good corrosion resistance. They are commonly used in aircraft structures, wing skins, and stringers.

The 6xxx series, also known as the aluminum-magnesium-silicon alloys, are known for their excellent formability, good machinability, and moderate strength. These alloys are commonly used in fuselage panels, wing skins, and stringers.

The 7xxx series, also known as the aluminum-zinc-magnesium alloys, are the highest strength aluminum alloys used in aerospace. They have high fatigue resistance and good corrosion resistance, making them ideal for use in wing skins, fuselage panels, and wing spars.

Each alloy has its own unique properties that make it suitable for different applications. For instance, 2024 aluminum is known for its excellent fatigue resistance while 7075 aluminum is one of the strongest available aerospace-grade alloys – making it a popular choice for fuselage components like wings or tail sections. 

What Are The Benefits Of Using Aluminum Alloys On Aircraft?

Aerospace aluminum provides several benefits, including:

  • Lightweight: Aluminum is significantly lighter than traditional steel and other metals, reducing the overall weight of the aircraft, leading to improved fuel efficiency and reduced operating costs.
  • High strength: Aluminum has high strength-to-weight ratios, making it ideal for use in critical components such as fuselage structures, wings, and landing gear.
  • Corrosion resistance: Aluminum has excellent resistance to corrosion, making it well suited for use in harsh aerospace environments.
  • Ductility: Aluminum has good ductility, which makes it ideal for use in components that need to withstand high-stress loads, such as wing skins and fuselage panels.
  • Manufacturing ease: Aluminum is easily machined and formed into complex shapes, making it an ideal choice for aerospace manufacturing.
  • Recyclability: Aluminum is fully recyclable, which makes it environmentally friendly and an attractive option for the aerospace industry.
  • Cost-effectiveness: Aluminum is cost-effective compared to other high-strength materials, making it an attractive option for aerospace manufacturers, particularly for small-scale production runs.

As you’ve no doubt gathered, the benefits of using aerospace aluminum include things like better performance, more efficiency, and lower costs. The aerospace industry continues to explore new aluminum alloys to leverage these advantages, and automation in air traffic control is also playing a crucial role in improving the performance and efficiency of the aerospace industry.

What are the Applications of Aerospace Aluminum

Aerospace aluminum is used in a variety of applications due to its lightweight, high strength, and corrosion-resistant properties. Some of the key applications of aerospace aluminum include:

  • Fuselage structures: Aluminum is used in the construction of aircraft fuselages due to its high strength-to-weight ratio, making it ideal for this critical component.
  • Wings: Aluminum is used in the manufacture of aircraft wings due to its excellent structural integrity and ability to withstand high-stress loads.
  • Landing gear: Aluminum is used in the construction of landing gear due to its high strength, which allows it to withstand the forces of landing and takeoff.
  • Engine parts: Aluminum is used in the manufacture of engine parts, such as fan blades and compressor disks, due to its lightweight, high-strength properties.
  • Other critical components: Aerospace aluminum is also used in the manufacture of other critical components, such as fasteners, hinges, and fittings.

It is clear that aerospace aluminum is an integral part of aircraft manufacturing and its importance is reflected in its widespread use throughout an aircraft. To ensure the quality and reliability of this critical material, it is crucial to source it from a trusted mil-spec supplier.

What Manufacturing Techniques Are Used for Aerospace Aluminum

Manufacturing techniques for aerospace aluminum play a crucial role in shaping the final product. The most commonly used manufacturing techniques for aerospace aluminum are:

  • Extrusion: This method involves forcing aluminum through a die to form a desired shape. It is an efficient way to produce complex shapes and is ideal for large-scale production.
  • Forging: This process involves heating aluminum to a high temperature and then shaping it under high pressure to form a desired shape. Forging is ideal for producing high-strength components and is commonly used for critical components such as engine parts.
  • Roll bonding: This technique involves bonding multiple layers of aluminum together to form a composite material. Roll bonding is ideal for producing lightweight and strong components, such as wing skins.

In addition to these techniques, aerospace aluminum can also be machined, cast, and formed through other manufacturing processes. Choosing the right manufacturing technique depends on the desired properties of the final product and the production volume. It is worth mentioning that 3D printing in Aerospace is increasingly being used as a manufacturing technique for aerospace aluminum. This cutting-edge technology enables the production of complex, highly customized components, making it an attractive option for aerospace manufacturers.

In Closing

In the aerospace industry, aluminum is one of the most commonly used materials. It’s lightweight, strong, and durable all qualities that make it a great choice for aircraft construction.

Overall, aluminum alloys offer many advantages when used on aircraft. They provide superior strength-to-weight ratios, excellent corrosion resistance, and increased fuel efficiency all things that make them a great option for aerospace applications. That being said, it’s important to consider other factors such as cost before settling on any material for use in an aircraft design.
