2024 T851 Aluminum Plate
2024 Alloy Aluminum Plate is probably the best-known and most widely used aircraft alloy. Because it has a high yield strength and relatively good fatigue resistance, it is easily used in structures and parts that require a good strength-to-weight ratio.
Due to its good machinability and superior grain structure, Alloy 2024 sheet is critical for precision fittings and parts. Although this alloy does not have good corrosion resistance, resistance welding is possible.
