EN AW-7010 – LOW-FATIGUE

EN AW-7010 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. Applications for this alloy include aerospace technology and mechanical engineering for components that have to withstand the highest loads. It should be noted that alternative joining techniques must be used, as this alloy is not weldable.

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. 85 HBW can be named as a guideline for cast material. The homogenised 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.
