7075 aluminium plates combine high tensile strength with low material weight, making them a preferred aluminium grade for demanding aerospace, defence, tooling and engineering applications. Renaissance Fittings & Piping supplies 7075 plates to ASTM B209 / ASME SB209 specifications, including 7075 T651 aluminium plates for applications specifying the T651 temper.
Plate enquiries are processed against the temper, thickness, width, length, quantity, surface condition and certification requirement. This is particularly important for 7075 because mechanical properties change with the temper and, for some tempers, with plate thickness.
7075 Aluminium Plate Specifications
| Parameter | 7075 Aluminium Plate |
|---|---|
| Alloy | 7075 |
| Product Form | Plate |
| Primary Specification | ASTM B209 / ASME SB209 |
| Temper Range | T3, T4, T5, T6, T651, T6511 |
| Thickness Range | 0.2–300 mm |
| Width Range | 100–2600 mm |
| Length Range | 500–10000 mm |
| Rolling Condition | Hot Rolled / Cold Rolled |
| Surface | Bright, polished, hairline, brushed, sand blasted, embossed, etched |
| Finish | Mill finish / specified finish |
| Coating | PVC, colour, polyester, fluorocarbon, polyurethane, epoxy |
The purchase specification should state the exact temper and plate dimensions rather than simply identifying the material as “7075 aluminium.”
7075 Aluminium Plate Tempers
Temper selection determines the mechanical condition of the 7075 plate and should be matched to the design specification.
| Temper | Primary Consideration |
|---|---|
| T3 | 7075 plate in the T3 temper condition |
| T4 | 7075 plate in the T4 temper condition |
| T5 | 7075 plate in the T5 temper condition |
| T6 | High-strength 7075 plate applications |
| T651 | Stress-relieved high-strength plate applications |
| T6511 | 7075 plate requirements specifying the T6511 condition |
| T7351 | 7075 plate requirements specifying the T7351 condition |
For a T7351 specification, see the dedicated 7075 T7351 aluminium plates page.
For the T651 condition, the dedicated 7075 T651 aluminium plates product page covers the specific plate specification, dimensions and thickness-dependent mechanical data.
7075 Aluminium Plate Mechanical Properties
The reference mechanical values below show why the temper must form part of the material specification.
| Temper | Tensile Strength | Yield Strength | Elongation | Hardness |
|---|---|---|---|---|
| T6 / T651 | 572 MPa / 83 ksi | 503 MPa / 73 ksi | 11% | 150 HB |
| T73 / T7351 | 503 MPa / 73 ksi | 434 MPa / 63 ksi | 13% | N/A |
For T7351 plate, properties are thickness dependent. The dedicated T7351 specification should therefore be used when the order requires that temper.
7075 Aluminium Plate Thickness and Dimensions
| Plate Parameter | Reference Range |
|---|---|
| Thickness | 0.2–300 mm |
| Width | 100–2600 mm |
| Length | 500–10000 mm |
For a quotation, the useful specification is the actual plate thickness × width × length, followed by temper and quantity.
For example: 7075 T651 aluminium plate, 25 mm × 1500 mm × 3000 mm, required quantity and certification.
This gives the supplier the information needed to check the relevant material and dimensional specification instead of treating the enquiry as a generic 7075 request.
7075 Aluminium Plate Weight
Theoretical weight calculated using an approximate density of 2.815 g/cm³:
| Thickness | Approx. Weight kg/m² |
|---|---|
| 0.50 mm | 1.41 |
| 1.00 mm | 2.82 |
| 1.50 mm | 4.22 |
| 2.00 mm | 5.63 |
| 2.50 mm | 7.04 |
| 3.00 mm | 8.45 |
| 4.00 mm | 11.26 |
| 5.00 mm | 14.08 |
| 6.00 mm | 16.89 |
| 8.00 mm | 22.52 |
| 10.00 mm | 28.15 |
| 12.00 mm | 33.78 |
| 15.00 mm | 42.23 |
| 20.00 mm | 56.30 |
| 25.00 mm | 70.38 |
| 30.00 mm | 84.45 |
| 40.00 mm | 112.60 |
| 50.00 mm | 140.75 |
| 60.00 mm | 168.90 |
| 75.00 mm | 211.13 |
| 100.00 mm | 281.50 |
Theoretical weight is useful for estimating material quantity. Final shipment weight depends on the ordered plate dimensions and dimensional tolerances.
7075 Aluminium Plate Chemical Composition
| Element | Minimum % | Maximum % |
|---|---|---|
| Silicon | — | 0.40 |
| Iron | — | 0.50 |
| Copper | 1.20 | 2.00 |
| Manganese | — | 0.30 |
| Magnesium | 2.10 | 2.90 |
| Chromium | 0.18 | 0.28 |
| Zinc | 5.10 | 6.10 |
| Titanium | — | 0.20 |
| Other, Each | — | 0.05 |
| Other, Total | — | 0.15 |
| Aluminium | Balance | Balance |
The principal alloying elements are zinc, magnesium and copper, which distinguish 7075 from lower-strength aluminium alloy plate grades.
7075 Aluminium Plate Equivalent Grades
| Standard | Designation |
|---|---|
| UNS | A97075 |
| EN | EN AW-7075 / EN AW-AlZn5.5MgCu |
| DIN / WNr | 3.4365 / AlZnMgCu1.5 |
| JIS | 7075 |
| AFNOR | 7075 A-Z5GU |
| ISO | AlZn6MgCu |
| BS | 7075 L95 / L96 |
| GOST | V95 |
These designations identify the 7075 alloy family. They do not replace the temper designation in a plate purchase specification.
ASTM B209 7075 Aluminium Plates
ASTM B209 / ASME SB209 is the principal material specification used for the 7075 aluminium plate range.
A technically complete enquiry should identify:
| Purchase Detail | Example |
|---|---|
| Alloy | 7075 |
| Temper | T651 / T7351 |
| Product | Plate |
| Thickness | 25 mm |
| Width | 1500 mm |
| Length | 3000 mm |
| Surface | Mill / specified finish |
| Quantity | Number of plates or required weight |
| Certification | MTC / inspection requirement |
This specification-based approach is more useful for procurement than searching only by the alloy number.

7075 is generally selected when the strength requirement is higher than that of common 5xxx and 6xxx aluminium plate grades.
7075 Aluminium Plate Cutting and Machining
Plate processing can be specified according to the finished component requirement.
- Cut-to-size plate
- CNC machining
- Drilling
- Milling
- Laser cutting
- Plasma cutting
- Oxy-propane cutting
