G.AL® 7075GF

High Strength , Precision Machined Rolled Plate G.AL® 7075GF

Alloy EN AW 7075 [AlZn5,5MgCu]
Type of Alloy heat treatable
Temper T651
Surface two surfaces precision milled, roughness Ra 0.4 µm, foiled on both sides

In certain applications, the use of higher-strength cast plates is not sufficient; high-strength rolled plates must be used. However, the problem with rolled plates is the wide toleration of thickness and flatness, which results in extremely complex processing. Precision rolled plate G.AL® 7075GF from alloy EN AW 7075 (AlZn5.5MgCu), finely milled on both sides and covered with protective foil, provides users with a semi-finished product which drastically reduces the time required for machining.

Special features

  • Very high strength
  • Narrow tolerances of thickness and flatness
  • Very good machinability
  • Very good hardness
  • Two sides precision machined surface

G.AL 7075GF Aluminium precision rolled plate for applications of the automation technology

Automation technology

In automation, for example rotary indexing tables, can often be economically produced from this semi-finished product due to the uniform flatness of G.AL® 7075GF.

Expert Tip

If components show a very high degree of machining and they must be highly accurate, there can be a problem with warping when using rolled plates. This risk can be minimised if the processed component is subjected to stress relief annealing after the roughing operation at 140 ° C for 2 hours and only then is finished.
