7XXX aluminium plate alloys contain zinc as the main alloying element, usually in combination with magnesium and copper. Arconic's range of high strength 7XXX aluminium plate alloys are widely used in aerospace structures and are approved by the world's leading airframe builders. For engineering applications these alloys are generally used in the T651 or T652 temper in order to provide maximum strength.
7XXX aluminium plate alloys are superseding steels in structural load bearing applications where the benefits of lightness, specific stiffness and high strength-to-weight ratio can be exploited.
- Machined components
- Load bearing structures, e.g. cargo containers
7XXX aluminium plate alloys, with excellent machinability and wear resistance are widely used for mould applications.
