For landing gear, considering the potential to support all the structure and cyclic loading during landing, the most important criteria design is high strength and fatigue resistance [1,2]. Aluminum alloys have been the best choice for commercial aircraft with a much more rapid insertion due to lower manufacturing costs, low replacing risk and the use of an existing production infrastructure. The 7xxx series are predominating alloys when strength is the primary requirement [3,4].
