Al 2024. 2024 aluminum is a versatile aluminum alloy, characterized by diverse tempers (or variants) of the grade, which constitute a group of materials. Aluminium alloy 2024 offers excellent toughness at moderately high strength levels.

This material type is used widely in the aerospace sector—most often in aircraft wing and fuselage structural parts (ribs, frames, ties) under tensile load—and also in automotive applications. The most commonly used temper designs include 2024t3, 2024t351, 2024t4, 2024 t6 and 2024t4.
