What are some alloys that contain a high proportion of aluminum for their strength and ductility?

Alloys that are known for their high aluminum content and possess excellent strength and ductility include 6061 aluminum alloy, 7075 aluminum alloy, and 2024 aluminum alloy. 6061 is widely used in structural applications due to its balance of strength, corrosion resistance, and formability. 7075 is one of the strongest aluminum alloys and is used in aerospace and high-strength applications. 2024 is known for its good mechanical properties and is used in aircraft structures and other demanding applications. These alloys leverage the benefits of aluminum, such as low density and high resistance to corrosion, while their specific compositions and heat treatments enhance their strength and ductility.
