CERTAL®, Al rolled plate



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 center and is therefore much more dimensionally stable than, for example, rolled plates made of EN AW 7075.
