Export Control Notice - These Grades Cannot Be Exported
7075 aluminum - including forged 7075-T6 - falls within these categories and is not available for export.
High-strength aluminum alloys of this class are listed under the export control regulations of the People's Republic of China for dual-use items and technologies. Shipping them out of China requires an export licence issued by the competent Chinese authorities. In practice a licence is not obtained for ordinary commercial orders in these categories, so GNEE does not export them.
GNEE does not export to any party or destination prohibited under applicable export control and international sanctions laws.
Control status technically turns on six variables: alloy grade, temper, product form, dimensions, quantity and intended end-use. Whatever the combination, none of the grades in the table below are available for export from GNEE.
Aluminum grades affected by these controls
| Alloy grade | Common temper(s) | Tensile strength (MPa) - reference |
|---|---|---|
| 7075 | T6 / T651 | 540 – 570 |
| 7075 | T73 / T7351 | 485 – 500 |
| 7075 | T76 / T7651 | 500 – 515 |
| 7050 | T7451 / T6 | 475 – 620 |
| 2024 | T351 / T4 | 425 – 470 |
| 7A04 | T6 | ≥ 530 |
| 2014 | T6 | approx. 460 – 500 |
| 2017 | T4 | approx. 390 – 480 (some specifications may reach higher) |
| 2195 | - | approx. 572 |
| 7068 | - | approx. 623 |
| 7055 | - | approx. 654 |
| 7150 | - | approx. 643 |
Strength values in this table are indicative reference ranges used for control classification. They are not specification minimums. The governing limits for any enquiry come from the applicable standard or your drawing.
What we can quote instead
We cannot accept export enquiries for the grades listed above. If strength is the reason you are looking at them, send us the load case, the service environment and the fabrication method, and we will quote a non-controlled substitute - usually from the 5xxx or 6xxx series - with properties that fit the job and no export restriction attached.
Introduction of 7075 aluminum sheet and plate
7075 is a heat-treatable aluminum alloy in the 7xxx series, with zinc as the main alloying element and added magnesium and copper. In the T6/T651 tempers it reaches the highest strength levels of the common wrought aluminum alloys, with a strength-to-weight ratio close to that of many low-alloy steels.
7075 is supplied as both sheet (thin, rolled) and plate (thick, often stress-relieved). For plate the stress-relieved tempers T651, T7351 and T7451 are standard because they reduce residual stress and the risk of distortion during machining. The alloy machines well, but its corrosion resistance is lower than that of 5xxx or 6xxx alloys and its fusion weldability is poor - both points are covered in the fabrication section.
Chemical composition of 7075 aluminum alloy
Composition limits below are per ASTM B209 and EN 573-3 (weight %). Aluminum is the balance.
| Element | Min (%) | Max (%) |
|---|---|---|
| Silicon (Si) | - | 0.40 |
| Iron (Fe) | - | 0.50 |
| Copper (Cu) | 1.2 | 2.0 |
| Manganese (Mn) | - | 0.30 |
| Magnesium (Mg) | 2.1 | 2.9 |
| Chromium (Cr) | 0.18 | 0.28 |
| Zinc (Zn) | 5.1 | 6.1 |
| Titanium (Ti) | - | 0.20 |
| Each other | - | 0.05 |
| Total others | - | 0.15 |

Mechanical properties of 7075 aluminum sheet and plate
Typical room-temperature values per ASTM B209. Values vary with thickness and temper; the figures below are representative for the stated product form. Confirm against the ordered thickness on the mill certificate.
| Temper | Product form | Tensile strength | Yield strength | Elongation |
|---|---|---|---|---|
| O | Sheet / plate | 276 MPa (40 ksi) | 145 MPa (21 ksi) | 10% |
| T6 | Sheet | 538 MPa (78 ksi) | 469 MPa (68 ksi) | 7% |
| T651 | Plate | 538 MPa (78 ksi) | 476 MPa (69 ksi) | 7–9% |
| T7351 | Plate | 469 MPa (68 ksi) | 400 MPa (58 ksi) | 7–10% |
| T7451 | Plate | 503 MPa (73 ksi) | 434 MPa (63 ksi) | 8–10% |
T7351 and T7451 trade a little tensile strength for much better resistance to stress-corrosion cracking, which is why they are preferred for thick plate in corrosive service.

Dimensional tolerances for 7075 aluminum plate
Tolerances follow ANSI H35.2(M). Because 7075 is an aerospace-grade alloy, plate is normally ordered to the tighter Table 3.1b limits; the values below are the commercial Table 3.1a reference for general plate (± mm). Tighter aerospace limits are quoted per purchase order.
| Thickness (mm) | Width ≤ 1000 mm | Width 1000–2000 mm |
|---|---|---|
| 0.40–0.63 | ±0.040 | ±0.06 |
| 1.00–1.20 | ±0.06 | ±0.09 |
| 3.20–4.00 | ±0.14 | ±0.18 |
| 6.30–8.00 | ±0.30 | ±0.36 |
| 10.00–16.00 | ±0.56 | ±0.56 |
| 25.00–40.00 | ±1.00 | ±1.20 |
| 60.00–80.00 | ±1.90 | ±2.20 |
Sheared width tolerance: ±2.5 mm up to 1000 mm wide, ±3 mm for 1000–2000 mm. Sheared length tolerance: ±2 mm up to 1000 mm, ±2.5 mm for 1000–2000 mm. Buyer-specified single-side tolerances are accepted and quoted case by case.
Applications of 7075 aluminum sheet and plate
7075 is chosen where the highest strength-to-weight ratio matters more than corrosion resistance or weldability:
Aerospace structures. Wing skins, spars, ribs, fuselage frames and bulkheads on commercial and military aircraft, where the high strength lets designers save weight.
Tooling, molds and fixtures. High-strength plates for injection molds, jigs, fixtures and precision machined parts that must hold tight tolerances.
Automotive performance parts. Chassis brackets, suspension arms and structural components on racing and high-performance vehicles where weight savings are critical.
Sporting and recreational equipment. Bicycle components, climbing hardware and other parts that benefit from low weight and high strength.
In corrosive or marine environments 7075 needs protective coating or cladding; specify T7351/T7451 and a surface treatment if the part sees sustained humidity or salt exposure.
Machining and fabrication of 7075 aluminum
7075 machines cleanly at high speeds with standard carbide tooling and gives a good surface finish, which is why it is widely used for precision parts. It forms reasonably in the O temper but work-hardens in the T tempers, so forming is normally done before heat treatment.
Weldability is poor. Fusion welding (TIG/MIG) is not recommended because it weakens the joint and can cause hot cracking and loss of corrosion resistance in the heat-affected zone. Where joining is required, use rivets, bolts or other mechanical fasteners; resistance welding can work for some assemblies. For any structure that must be welded, discuss the service condition with our engineers before ordering.
Heat treatment follows the standard solution-treatment-and-aging route; the T73/T74 tempers use an over-aging step that improves stress-corrosion resistance at a small strength cost.
