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

• Mechanical engineering

• Defense technology

Moulds (cold dimensions)

Turned billets

We can produce all diameters between 140 - 1080 mm.

Mechanical properties

There is no standard for cast round rods (cast billets / bolts) that defines mechanical properties. A Brinell hardness in the homogenised state of approx. 83 HBW can be named as a guideline for cast material. The homogenized state (=”O3“ according to EN515) is comparable in strength with the annealed state (=”O“) for extruded products. The final strength is essentially adjusted by the reshaping process and/or the heat treatments by our customers.
