High-strength Rolled Plate
|Alloy||AA 7122 [AlZn5Mg3Cu]|
|Type of Alloy||heat-treatable|
|Temper||T651 / T652|
The high-strength rolled plate CERTAL SPC® is made of alloy AA 7122, a modified version of alloy EN AW 7022 (AlZn5Mg3Cu) and is available at up to 11.8 in. thickness. The 5.9 to 7.1 in. thicknesses are produced both in stretched (T651) or compressed (T652) versions, from thicknesses >7.1 in. always in T652. Compared with other high-strength rolled plates, CERTAL SPC® 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.
- Very high strength
- Very low strength decrease over the cross section
- Excellent polishing properties
- Very good machinability
- Good dimensional stability
Whether for casting, injection molding or blow molds for plastics processing proceeds, in medium-sized series or mass production, CERTAL SPC® is probably the best suited material.
For example, for heavy-duty tool carriers, tool changers and tool clamps, CERTAL SPC® is an excellent choice.
In hydraulics, CERTAL SPC® takes into account the rolling direction for control blocks to peak pressures of 400 bar.
Different versions of gripping claws, clamping and tensioning devices for heavy loads are produced from CERTAL SPC®.
If rolled plates must be bent or canted, the bending edge should always be transverse to the rolling direction to avoid material breakage or formation of hairline cracks. Under no circumstances may the bending edge be marked with a sharp object, e.g. scribers. Rolled plates made of EN AW 5754 and 5083 are very-well suited, while Al cast plates are not suitable for bending and canting because of their structure.Sven Flaake, Technical Product Manager, GLEICH Aluminium
