Alloy 2124 aluminum plate is a high purity form of 2024 and is normally supplied in 1.50 6.00 plate. Available in T851 temper, this plate alloy exhibits good strength retention and creep resistance at elevated temperatures up to 350 degrees. Fracture toughness levels of 2124-T851 plate are significantly higher than 2024-T851. This alloy is recommended for those applications requiring better short-transverse ductility, high strength and good machinability and has excellent exfoliation corrosion resistance. Fatigue properties of alloy 2124-T851 are similar to those of 2024-T851.
