6061 alloy is the earliest 6-series aluminium alloy with good corrosion resistance and weldability, but low strength. Compared with 6061 alloy, the tensile strength of 6013 aluminum alloy plate sheet in T6 state is increased by 15%-20%. It has the same weldability as 6061 alloy. The yield strength, fatigue strength and fracture property of T6 alloy sheet without aluminium cladding are better than 2024 T3 alloy sheet with aluminium cladding, and the fatigue crack growth rate is lower. In addition, the aging treatment of 6013 alloy from T4 to T6 is relatively simple. Available specs:
Alloy: 6013
Temper: T6
Thickness: 0.5--1.5mm
Width: 1250--2650mm
Length: 1300--6500mm

Therefore, 6013 aluminum alloy plate sheet can replace 2024 and 6061 alloy in aircraft fuselage. For example, 6013 alloy can replace 2024 aluminum alloy wrapped on P7-A of US Navy Anti-submarine Patrol Aircraft. It can be used as fuselage skin, rib, pressure compartment skin, front and rear edge, door and window skin, wing, short cabin fairing and short cabin skin.
