The 2024 alloy is primarily composed of copper, which gives it its notable strength, along with magnesium and manganese. This specific blend results in a material with an excellent strength-to-weight ratio, making it significantly stronger than many other aluminium series. While it offers outstanding fatigue resistance, it’s important to note that its corrosion resistance is generally lower than that of other alloys, often necessitating protective coatings for certain environments to ensure long-term performance in demanding situations.
