Aircraft Aluminum Alloy 2024

What Is Aircraft Aluminum Alloy?

Aircraft aluminum alloy is an ultra-high-strength deformed aluminum alloy widely used in the aviation industry. It surpasses ordinary aluminum alloys in strength, hardness, toughness, fatigue resistance, and plasticity. This alloy has excellent mechanical and processing properties, good plasticity after solution treatment, and effective heat treatment strengthening. It is considered an ideal material for aviation structures due to its high strength and good toughness.

Aluminum Alloy 2024

Aluminum alloy 2024 is a typical duralumin alloy, specifically an Al-Mg-Cu aluminum alloy. Its composition includes 4.5% copper, 0.6% manganese, and 1.5% magnesium. This combination provides a balanced composition and good overall performance.

Key features of 2024 aluminum alloy include high strength and a certain degree of heat resistance, making it suitable for parts that operate below 150°C. Notably, when the temperature exceeds 125°C, its strength surpasses that of the 7075 aluminum plate. The alloy exhibits better forming performance in hot temper, annealed, and newly quenched states. Additionally, it has a significant heat treatment strengthening effect, though the heat treatment process must be strictly followed.
