Aluminium Alloy 2618A (Aluminum 2618) is a high strength aluminium alloy which contains both copper and magnesium. Alloy 2618 (2618A) has good machinability and is fair resistance to atmospheric attack. Aluminium Alloy 2618A (Aluminum 2618) is typically used in aerospace and defence components. It is commonly used for pistons and rotating aircraft parts due to it's ability to work in higher temperature applications. 2618 is also used in high performance autosport applications.
