Aluminium alloys for the aerospace industry

Choosing the right alloys, whether aluminium or magnesium, is crucial for achieving the best end result. Numerous factors play a role in realizing a good product. The key question is: Where and for what purpose is the aerospace customer going to use the component?

Alloys for the Aerospace industry

There are hundreds of aluminium alloys. Many aerospace customers ask for a specific alloy when placing an order. We then always respond with the following counter-question: why do you want to make the product specifically with this aluminium alloy? Another alloy might be a better choice to consider for the Aerospace industry.

Choosing the right aluminium alloy for the Aerospace industry depends on several factors. The most important of which is the purpose of the product. This key question the leads on to other further questions:

  • How strong does the final product need to be?
  • Is the component going to be visible or not? In other words: is it important thtat the surface looks good?
  • How important is the elasticity?
  • Does it need to be corrosion resistant?
  • Is the conductivity of heat and / or electricity an important consideration?
  • In which temperature will the end product be used?

The answers to these questions from our Aerospace customers are important to be able to choose the right aluminium alloys. Another factor also plays a role: the construction of the product. Complex products with, for example, small cores, thin wall thicknesses, and narrow tolerances are not possible to make with a hard and less malleable alloy.

6061, 6082, and 7075 alloys for the aerospace industry

Mifa offers a standard range of aluminium alloys. With this e produce more than 95% of our products. Our standard range of fourteen aluminium alloys, consists of alloys from the following series: 1xxx, 3xxx, 6xxx, and 7xxx.

The 6xxx series

Alloys from the 6xxx series contain silicon and magnesium. In general, the more magnesium and the more silicon that are added to the aluminium, the stronger the end product will be.  These alloys are frequently chosen as they have good weldability, corrosion resistance, machinability, anodizability, and electrical conductivity.

We work with the following alloys: 6060, 6063, 6005A, 6061, 6082 and the specials: 6066 and 6463. 6061 and 6082 are alloys commonly used in the aerospace industry because of their extra strength. These are alloys that are prescribed by the aviation authorities. These alloys are particularly used by Airbus and Boeing for aircraft interiors.

The 7xxx series

Our standard range includes 7020, 7022 and 7075 from the 7xxx series. As well as aluminium, the 7020 consists of magnesium and zinc. Copper is also added to the 7022 and 7075. These alloys can be hardened and are some of the strongest we have. However, once again, they have reduced malleability and are therefore not suitable for complex products that require high precision. 7075 is a very strong alloy that is commonly used in the aerospace industry for structural parts.

Worldwide supply to aerospace customers thanks to AS 9100 certificate

Mifa produces high quality extrusion profiles for customers such as B/E, Diehl, EADS, Thales, and many others. To do this, we not only carry out a process control but also a strict product control. The Aerospace market sets stringent requirements for the quality of the surface, the strength of the material, and the weight of the precision profiles. Mifa possesses the AS 9100 quality certification for the aerospace industry. This certification is also known by the name 'EN 9100'.  Read more about our AS 9100 certification here.

100% aerospace proof

The precision of Mifa has many advantages. The biggest is the enormous amount of freedom in construction. Asymmetrical shapes are no problem, just like varying and very thin walls. Even the most complicated constructions are possible. And post-processing is rarely necessary, seeing as we deliver precision. This eliminates the need for grinding, milling, and other operations, as well as extra costs.

Another advantage of aluminium is that you can go thinner than with plastic as aluminium is a stronger material. It is also light, does not rust, and is good looking, with its high-tech gleaming look. If we need to do some post-processing, a surface treatment, or assembly after all, we can often do those things in house.
