2124 Aluminium Plates
Alloy 2124 aluminum plates are a high purity form of 2024 and are 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.
Applications
• Machined fuselage bulkheads
• Wing skins in high-performance military aircraft
• Wing skins in high-performance military aircraft
