Rolled plate
Ergal
EN AW 7075

Ergal is available in a hardened, stretched, and tempered state (T651) in thicknesses of up to 200 mm. For greater thicknesses there are rolled materials that are not pulled; cold compress or forged materials that are quite unstable during processing and are replaced by innovative molten or cast products.

Ergal is also available in extruded or cast and machined round bars in diameters of up to 500 mm.
