EN AW-2618 / A
EN AW-2618 / A – TEMPERATURE-RESISTANT
EN AW-2618 / A belongs to the group of heat-treatable alloys. Therefore, it is necessary to carry out a heat treatment such as solution annealing followed by artificial aging. Only then can the alloy develop its full potential. This alloy, developed specifically for aerospace engineering, has high strengths, good machinability and average corrosion resistance. Due to its high temperature resistance,
it is often used in areas where high strength is required at temperatures up to 300 °C. For example, we are able to restrict beryllium by a factor of 500.
EN AW-2618 / A applications
Due to its high-temperature resistance, EN AW-2618A is often used in turbine or engine construction. Wherever high strength is required at elevated temperatures.
Application areas
- High-strength structural parts in aviation
- Defense technology
- Mechanical engineering

Turned billets
We currently offer all diameters from 140 – 650 mm. From Q2 2023, we will be able to offer diameters up to 1,100 mm.
Mechanical properties
There is no standard for cast round rods (cast billets/bolts) that defines mechanical properties. A Brinell hardness of approx. 83 HBW in its homogenized state serves as a reference value for the cast material. The homogenized state („O3“ in accordance with EN 515) is comparable to the “soft annealed” state („O“) for extruded products. The final strength is adjusted by our customers‘ forming processes and/or heat treatments.
