CERTAL®
for high demands
on strength
High-strength Rolled Plate
Alloy:EN AW-7022 (AlZn5Mg3Cu)
Type of alloy: heat treatable
Temper: T6 / T651
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.

Drive technology
For drive units with very high power transmission, only high-strength materials can be used. In addition to strength, CERTAL® also offers good dimensional stability for this strength class.

Handling machines and industrial robots
If heavy loads have to be moved, CERTAL® has proven itself to be a high-strength material.

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.
