Aluminium 2024 Alloys - UNS A92024 / AMS 4037 / AMS 4121 / AMS 4117 / DIN 3.1355 / EN AW-2024 / BS L95

Aluminium 2024 Alloys, also known as UNS A92024 or AMS 4037, is a copper-based aluminium alloy known for its excellent strength-to-weight ratio and outstanding fatigue resistance. This makes it a preferred choice for applications in aerospace and structural engineering. While general welding is not ideal for this alloy, it can be effectively joined using friction welding methods.

To restore ductility and relieve stress after cold working or heat treatment, Aluminium 2024 undergoes an annealing process. This typically involves heating the alloy to a temperature between 399°C and 427°C for about two hours, followed by slow furnace cooling. During intermediate annealing between forming steps, the alloy is heated to 343°C for two hours and then air-cooled.
