EN AW-7050 is a hardenable aluminium wrought alloy designed for high-load applications in aerospace and mechanical engineering.

To unlock its full potential, heat treatment such as solution annealing and artificial aging is required. This alloy is non-weldable and alternative joining techniques such as riveting are required.

We offer EN AW-7050 turned billets in diameters ranging from 140 mm to 1,080 mm, tailored to meet your specific needs.

EN AW-7050 applications

EN AW-7050 used for components that must withstand the highest stresses. Typical applications include:

• Aerospace and defence technology: High-stress aircraft components, e.g. scots.
• Mechanical engineering: Components that are exposed to very high mechanical stress, as well as structural elements.
• Defence: Used in components that place the highest demands on strength and toughness.

Mechanical properties

The mechanical properties of EN AW-7050 make it suitable for a high-stress applications. Although there is no standard for cast round rods, a Brinell hardness of approximately 100 HBW in the homogenised state serves as a reference value for cast material. This state is comparable in strength to the annealed state ("O") for extruded products. Final strength can be adjusted through reshaping processes or heat treatments performed by our customers.
