Aerospace aluminium alloys for every component

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

Choosing the right aviation aluminium alloy plays a crucial role during the production process of aircraft. Aerospace aluminium refers to a group of aluminium alloys used in the aerospace industry. These alloys have properties like corrosion resistance and a high strength-to-weight ratio, which are of great importance in aviation engineering. Each alloy possesses a diverse set of properties that vary for each end application.

Important properties of aerospace aluminium alloys

Whether you value corrosion resistance or weldability, the right alloy is important for the final product. So, although Mifa offers aerospace grade aluminium, it is still 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, weight, safety, and appearance is important in most cases. Consistency in quality is also important

Aviation alloys for high-quality aerospace parts

Several aluminium alloys are especially interesting for aerospace applications because of their attributes. Details about these alloys are as follows:

6061 aluminium

Aluminium 6061 is a versatile alloy widely applied in aerospace. It offers a good balance of strength and corrosion resistance, while also being easy to machine and process. This makes it suitable for a broad range of structural parts.

7020 aluminium

Aluminium 7020 stands out for its excellent corrosion and fatigue resistance. This alloy is well suited for aerospace structures that must perform reliably under demanding conditions over long service lives.

7022 aluminium

Aluminium 7022 is designed for high-load aerospace applications. With strong mechanical properties and very good fatigue resistance, it is the preferred choice for parts where strength and durability are essential.

7075 aluminium

Aluminium 7075 is known for its very high strength. It is often used in aerospace applications where maximum performance is required, such as in heavily loaded structural components. Despite its strength, it remains lightweight and reliable.
