CERTAL®
High-strength Rolled Plate
| Alloy | EN AW 7022 [AlZn5Mg3Cu] |
| Type of Alloy | heat treatable |
| Temper | T651 |
| Surface | rolled |
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.
Special features
- Very high strength
- Good protective anodising capability
- Very good machining properties
- Very good polishability
- Good dimensional stability

Applications
Toolmaking
CERTAL® is often used for heavily-loaded anvil caps and punch retainers.
Device construction and mechanical engineering
Due to the very high strength, CERTAL® is preferred for use in workpiece clamping and machining devices.
Handling machines and industrial robots
If heavy loads have to be moved, CERTAL® has proven itself to be a high-strength material.
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.
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. rd.
