2618 aluminum is a copper-alloyed aerospace aluminum alloy designed for elevated-temperature service, offering high strength retention up to approximately 300°C in forged and cast applications. The T61 temper provides solution heat treatment and artificial aging, delivering optimal strength and creep resistance for gas turbine engines, compressor housings, and other high-temperature structural components.
