This tabular reference presents chemical composition and mechanical-property data for wrought aluminum alloys commonly used in aerospace work. Composition entries cover 1100, 2017, 2024, 2117, 3003, 5052, 5056, 6061, and 7075, including silicon, iron, copper, manganese, magnesium, chromium, zinc, and aluminum. A second table lists strength limits and Brinell hardness for annealed, strain-hardened, naturally aged, artificially aged, and Alclad conditions, allowing direct comparison of alloy and temper combinations. The article preserves the source’s reported process conditions, units, material grades, and technical relationships for practical reference.
