Rolled plate Ergal (EN AW 7075) data sheet
Ergal is available in a hardened, stretched, and tempered state (T651) in thicknesses of up to 200 mm.
 
Ergal 7075 is used for the construction of production moulds, as well as machinery and equipment that's subjected to significant static and dynamic stresses.

The main alloying element, which guarantees maximum hardness, is zinc; this alloy is also often used as a replacement for soft steels.

AVAILABILITY

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.

  • Rolled plates
  • Extruded round bars
  • Cast and turned round bars
