EN AW-7075

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

  • Tool, mold and model making
  • Aerospace industries
  • Defense technology

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. 46 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.

Overview of all technical data and facts about EN AW-7075

Larger diameters up to 1,100 mm, more sophisticated alloys, new compositions: LEICHTMETALL is continuously pushing the limits of technical possibilities.

Customer-specific solutions …

We will also be happy to adapt the analysis specifications to your highly individual processing and quality requirements on request. Various chemical compositions can be realized, as well as very pure alloys containing only small amounts of certain elements, such as sodium, calcium or beryllium. We are looking forward to your request!

… no problem for LEICHTMETALL

High-strength aluminum alloys are our specialty. Our foundry expertise goes back over 90 years. Both then and now, demanding customers from many sectors such as aircraft construction, the automotive industry, mechanical engineering and the energy sector use our premium alloys made in Hanover, Germany. Sustainability is very important to us: Our processes are comprehensively energy and environmentally conscious. Therefore, we mainly work with secondary aluminum from the recycling economy to ensure greater environmental and climate protection.
