Alloy 2024 aluminum plates are perhaps the best known and most widely used aircraft alloy. Since it exhibits high yield strength and relatively good fatigue resistance, it is readily used on structures and parts where good strength-to-weight ratio is desired. Because of its good machinability and superior grain structure, Alloy 2024 plate is essential for precision fittings and parts. Though this alloy does not have good corrosion resistance, welding by resistance method is feasible. Typical specifications are ASTM B209, AMS-QQ-A-250/4 and AMS4037.
