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.
Applications
Toolmaking
CERTAL® is often used for heavily-loaded anvil caps and punch retainers.
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.
Device construction and mechanical engineering
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.
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.
