EN AW-7075 – HIGH-STRENGTH

Our EN AW-7075 alloy belongs to the group of high-strength, heat-treatable alloys. Therefore, it is necessary to carry out a heat treatment such as solution annealing followed by artificial aging. This allows the alloy to develop its full potential and its strength is increased many times over. Its particularly high strength makes EN AW-7075 ideal for structural components in aerospace and defense.

Corrosion protection is recommended for applications in external environments.

EN AW-7075 applications

The proportion of aluminum in modern vehicles has increased by around 300% in the last twenty years. For example, two-thirds of a Formula 1 racing car is made of aluminum – despite fierce competition from carbon or titanium. Here, above all, 7000-series alloys are breaking into classic steel domains and replacing lightweight B-pillars in cars, for example. Its particularly high strength makes EN AW-7075 ideal for structural components in aerospace and defense.

Application areas

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. 70 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.
