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. 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 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
