2618 aluminum is a copper-aluminum alloy with magnesium and iron additions designed for elevated-temperature aerospace applications, offering strength retention up to 300°C. The T61 temper (solution heat-treated, artificially aged, and stress-relieved) provides optimal combination of tensile strength and thermal stability in die-forged components for aircraft engines and gas turbine applications.
