Material Description
EN AW-2618A is a heat-treatable aluminium alloy primarily used for aerospace, engine and motorsport components operating under elevated temperatures. Unlike alloys such as EN AW-7075, its main advantage is not maximum room-temperature strength, but its ability to retain mechanical properties at temperatures around 200 °C and above. It has good machinability and works best with sharp, polished aluminium geometries. Typical applications include forged pistons, rotating engine components and other thermally loaded parts.
