Aluminium alloy for aerospace industry

Considering factors like weight, strength and corrosion resistance, which specific grade of aluminium is best suited for fuselage construction in aerospace engineering?

Solved by Attila Szucs
Different aluminium alloys can meet your requirements for this application, such as aluminium 7075. It is widely regarded as the go-to material because of its impressive strength-to-weight ratio, perfect for heavy loads. It also has a great corrosion resistance. But you might also consider aluminium 6061 since it has better machinability and weldability.

        What about aluminium alloy 6063?

        6063 aluminium alloy is indeed often used for fuselages and aircraft wings, and it provides the lightweight characteristics necessary for fuel efficiency. But the 6063 alloy has a considerably lower yield strength (241 MPa) compared to the 7075 alloy (503 MPa), and slightly less than 6061 (276 MPa).
