Metallurgy has a vital role in the enlargement of aviation. Aluminum plays a major role in aircraft construction due to its excellent strength-to-weight ratio and cost ratio. It is especially suitable for aircraft manufacture because it is considered as one-third the weight of steel, allowing an aircraft to import maximum weight or renovate the efficiency of fuel consumption. Aluminum alloys have remarkable quality for use in the fuselage, wing and the erection of commercial airliners, military cargo and aircraft. The fabricated and fashioned aluminum are used in structural components of aircraft for the United States Navy. Aluminum can be used as a crucial propellant for motors of space shuttle as its volumetric energy density is great and very hard to burn. The strength of aluminum enables it to substitute heavy metals without loss of strength along supplementary metals (Aboulkhair 2019). Moreover, load-carrying assemblies can yield the benefit of the strength of aluminum to promote aircraft fabrication more consistent with reduced cost. Aluminum is extremely resistant to corrosion as well as to chemical reactions; hence, it is unambiguously suitable for aircraft operations in extremely corrosive environments. The 6063 aluminum is known for promoting prototypical quality attributes, and it is the most suitable alloy for anodizing solicitations. The recipient choice for aerospace applications is Al-7050, as it preserves its strength and properties in wider segments and provides protection against fractures and corrosion.
