The traditional material known as aluminum is often too soft to meet the requirements of certain applications, especially when considering aeronautic applications. These structural demanding applications thereby require the making of aluminum alloys which are structurally tough materials. Aluminum alloys are made to increase mechanical strength, increase corrosion resistance of the material, and thus increase overall shock survivability of the material (Subodh, K. D. , 2007).
Here, we are concerned with Aluminum alloys 2024 and 7075 which are particularly used in aircraft structures, and aerospace applications. The review presents the similarities and differences of each material with regards to their chemistry, processing, and heat treatment measures. Aluminum 2024 The aluminum 2024 was first introduced in 1931, and was available as an alclad sheet and plate forms. Due to its high corrosion resistance, the material is often used in areas of an aircraft where fatigue resistance and strength are required. Those areas include fuselage, wings, shear webs, and ribs of an aircraft.
As an alloy, aluminum 2024 is made up of several materials among which are aluminum, chromium, copper, iron, magnesium, manganese, zinc, and silicon. Such a composition gives the ending material adequate mechanical and thermal properties demanded for aircraft structural components. However, the material is also used for truck wheels, screw machine products, scientific instruments, and orthopedic equipment. Overall, the aluminum 2024 material may be used in any application where there is a need for high strength to weight ration materials, and/or structures.
