2618 aluminum alloy is a high-strength aluminum alloy primarily composed of aluminum, copper, and small amounts of other elements such as magnesium, silicon, and manganese.
2618 aerospace aluminum is a high-strength aluminum alloy belonging to the 2xxx series, with copper (Cu) as the primary alloying element, and often includes magnesium (Mg), silicon (Si), and a small amount of zirconium (Zr).
2618 aluminum forgings typically require heat treatment to achieve optimal mechanical performance. Common heat treatment methods include aging and quenching.
