EN AW 7075
High-strength Rolled Plate
| Alloy | EN AW 7075 [AlZn5,5MgCu] |
| Type of Alloy | heat-treatable |
| Temper | T6 / T651 |
| Surface | mill-finished or brush-finished |
High-strength rolled plate EN AW 7075 (AlZn5.5MgCu) is probably the most famous (high-strength) rolled plate and is used regardless of the individual requirements in nearly all sectors of the capital goods industry. In material state T7351, it is also suitable for applications where there is a risk of stress corrosion cracking (SCC). The problem is the enormous strength and hardness drop across the plate cross section from about 120 mm in thickness.
Special features
- Very high strength (but drop of the core strength for plates >80mm thickness)
- Ideally suited for structural etching
- Excellent polishing properties
- Very good machinability

Applications
Mould-making
For medium-sized series and mass production, in particular blow moulds for plastics processing and PUR foam moulds are preferably made of rolled plate EN AW 7075.
Mechanical engineering
As with all highly-stressed components, e.g. tool carriers, tool changers, tool clamps, etc., rolled plate EN AW 7075 is often used.
Toolmaking
Highly-loaded anvil caps, punch retainer and embossing plates are often made of rolled plate EN AW 7075.
Industrial robots
Different versions of gripping claws, clamping and tensioning devices for heavy loads are produced from rolled plate EN AW 7075.
Expert Tip
All rolled plates have directional properties and, in some cases, a serious decrease in strength and hardness from approximately 80 mm. This can lead to distortion as early as in the machining process. Wherever possible, G.AL® products should be used.
