EN AW-7050 – ENDURANCE

EN AW-7050 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 such as riveting must be used, as this alloy is not weldable.

EN AW-7050 applications

Applications for the EN AW-7050 alloy include aerospace technology and mechanical engineering for components that have to withstand the highest stresses.

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. 100 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.

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.
