Aerospace aluminium alloys for every component

Mifa offers various aluminium alloys, including aerospace alloys for the aerospace industry.

In the aviation market, choosing the right aluminium alloys for aircraft plays a crucial role during production. Tailored for high strength and resilience, these alloys are the backbone of today’s aircraft designs. Each alloy possesses a diverse set of properties that vary for each end application.

Important properties of aerospace aluminium alloys

Whether you are looking for an alloy that is highly corrosion resistant or that has the best weldability, the right choice of alloy is closely related to the end product. It is therefore important to know what properties the various alloys have. Alloys differ in various factors such as:

Heat resistance
Corrosion resistance
Mechanical strength
Conductivity
Weldability

But also strength, deformability, and surface condition are important elements. In the aerospace industry, aspects such as lightweight, safety, and cosmetic appearance, as well as consistent quality, are also extremely important.

Our expertise in aerospace aluminium alloys

In the aerospace industry, aluminium alloys 6061 and 7075 are preferred for extrusion profiles because of their excellent combination of strength, corrosion resistance and machinability. Aluminium alloy 6061 is valued for its versatility in aerospace applications, while aluminium alloy 7075 stands out in applications requiring maximum strength.

In addition, aluminium 7020 and 7022 are also well suited for aerospace applications, with alloy 7020 being characterised by its improved corrosion and fatigue resistance. In turn, aerospace aluminium 7022 is particularly suitable for high-load components thanks to its high mechanical properties and good fatigue resistance.

Lightweight aluminium profiles

Through our precision extrusion, we can create thin-walled, lightweight profiles for our customers in the aerospace industry. These thin-walled profiles provide a sustainable solution by reducing the CO2 emissions of an aircraft. Our EN AW 6061 and EN AW 6082 alloys for thin-walled extrusion profiles are an excellent example of our commitment to sustainability.
