CERTAL®

for high demands
on strength

High-strength Rolled Plate

Alloy:EN AW-7022 (AlZn5Mg3Cu)

Type of alloy: heat treatable

Temper: T6T651

Surface: rolled

  • very high strength 
  • good protective anodising capability
  • very good machining properties
  • very good polishability
  • good dimensional stability

High-strength rolled plate CERTAL® is based on alloy EN AW-7022 (AlZn5Mg3Cu). Compared with other high-strength rolled plates, CERTAL® has a significantly lower strength and hardness decrease from plate edge to centre and is therefore much more dimensionally stable than, for example, rolled plates made of EN AW-7075.

Expertentipp

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. rd.
