Copper‐based alloys are widely used in aircraft engineering, mainly in electrical components, due to its reliability and multitude of uses making them one of the most important metals in the aviation industry. The Copper has enough strength to be moulded but it is also tough enough to not break and the malleability of it can be formed and stretched so that it can go back into its original form with major issues. The high conductivity of Copper ensures that an electric current can be carried very freely.
Throughout the year, the aerospace industry has become more demanding in material requirements, leading to the development and use of many different alloys. Industry experts have a positive outlook about the future of Aluminium alloys in aerospace, projecting demand for Aluminium will double during the next decade.
2024: The alloy has a high yield strength and is a high-grade alloy with excellent fatigue resistance. It is commonly used in sheet form for the wings and fuselage.
2014: It is known for its strength and toughness but is susceptible to corrosion. As such, it’s often used inside the framework rather than the shell, it is suitable for arc welding.
5052: This is a non-heat treatable grade of alloy. It provides the highest strength and is highly ductile as well. It can be formed into various shapes and is highly corrosion resistant.
6061: It is commonly used in light crafts. Its easy machinability and welding are some of the reasons why it’s often preferred for these applications. It is fairly strong and features prominently in the wings and fuselage of the planes.
7050: For its high corrosion resistance and strength in wide sections, it is commonly used in the wing skins and fuselage and more so in military crafts
