Champak industries supplier of 7475 Aluminium Plates/ 7475 Plate is available in T651, T7651 and T7351 tempers. Alloy 7475 aluminum plates are a controlled toughness alloy whose values are 40 percent greater than alloy 7075 in the same tempers. This alloy's corrosion resistance and fatigue behavior are also equal to, or better than, many of the other high strength aerospace alloys, and is for those applications that require a combination of high strength, superior fracture toughness and resistance to fatigue crack propagation.
Reading the text: “Values” here means fracture-toughness values; the page does not say which tests or tempers the comparison is based on. Ask for test data.
7475 Aluminium Plates: Purchasing Specification
| Requirement | What to specify |
|---|---|
| Alloy and temper | State both, for example 5083-H116 or 6061-T651; properties depend on the temper. |
| Standard | ASTM B209 / ASME SB209 for plate and sheet, or EN 485 / EN 573; ASTM B928 for marine-service plate in the high-magnesium alloys, as the pages cite. |
| Dimensions | Thickness × width × length in mm or inches; number of plates or total weight. |
| Cutting | Sawing or waterjet cutting to your drawing; give tolerances and edge finish. |
| Welding | Weldability depends on the alloy: the 5xxx and 6xxx alloys weld readily, while high-strength 2xxx and 7xxx alloys are generally not arc-welded. State the process. |
| Documents | Mill test certificate (EN 10204 3.1) with chemistry, temper and mechanical properties. |

How the Eighteen Aluminium Alloys Differ
The eighteen pages cover aluminium alloys from several families. The 1xxx, 3xxx and 5xxx alloys are non-heat-treatable and gain strength by cold work, while the 2xxx, 6xxx and 7xxx alloys are heat-treatable. The 5xxx magnesium alloys are the usual marine and welded-structure choice; the 2xxx and 7xxx alloys are the high-strength aerospace alloys.
| Alloy | Family and hardening | Typical use (from the pages) |
|---|---|---|
| 1050A | 1xxx pure aluminium (99.5%), non-heat-treatable | General sheet-metal work, packaging, heat transfer, kitchenware |
| 1350 | 1xxx electrical-grade aluminium (99.5% min), non-heat-treatable | Transformer and switchgear conductors |
| 2024 | 2xxx aluminium-copper, heat-treatable | Aircraft structure, precision fittings, truck wheels |

| 2219 | 2xxx aluminium-copper, heat-treatable | Space boosters, fuel tanks, high-temperature structures |
| 3003 | 3xxx aluminium-manganese, non-heat-treatable | Heat exchangers, catwalks, food and chemical equipment, roofing |
| 5052 | 5xxx aluminium-magnesium, non-heat-treatable | Fuel tanks, truck panels, small boat hulls, pressure vessels |
| 5083 | 5xxx aluminium-magnesium (4.0–4.9% Mg) | LNG ships, pressure vessels, storage tanks, welded structures |
| 5086 | 5xxx aluminium-magnesium (3.5–4.5% Mg) | Shipyard work, tank cars, patrol and work-boat hulls |
| 5154 | 5xxx aluminium-magnesium (3.1–3.9% Mg) | Wire, rivets and cold-heading applications |
| 5454 | 5xxx aluminium-magnesium (2.4–3.0% Mg) | Road transport, chemical plant, pressure vessels, marine and off-shore |
| 5456 | 5xxx aluminium-magnesium (about 5% Mg) | Welded structures, low-temperature service |
| 5754 | 5xxx aluminium-magnesium (2.6–3.6% Mg) | Treadplate, shipbuilding, vehicle bodies, food processing |
| 6061-T6 | 6xxx aluminium-magnesium-silicon, heat-treatable | Tooling plate, architectural, transport, welded structures |
| 7050 | 7xxx aluminium-zinc-magnesium-copper, heat-treatable | Aerospace fuselage frames and bulkheads |
| 7075 | 7xxx aluminium-zinc, heat-treatable | Airframe structures and highly stressed parts |
| 7175 | 7xxx aluminium-zinc, heat-treatable forging alloy | Structural fittings, bolts and rivets |
| 7475 (this page) | 7xxx aluminium-zinc, controlled toughness, heat-treatable | Wing spars and fuselage bulkheads |

7475 Aluminium Plates: Frequently Asked Questions
01What is 7475 Aluminium Plates?
7475 is a controlled-toughness aluminium-zinc alloy plate in T651, T7651 and T7351 tempers, for applications needing high strength, high fracture toughness and resistance to fatigue crack propagation, such as wing spars and fuselage bulkheads.
02How does 7475 compare with 7075?
The page says its values are 40 percent greater than 7075 in the same tempers, and that corrosion resistance and fatigue behaviour are equal to or better than many other high-strength aerospace alloys.
03Which applications are listed?
Wing spars and fuselage bulkheads.
04What strength does the page list?
For 1.001–1.5 inch plate: tensile strength 78 ksi, yield strength 68 ksi and elongation 9%; the temper is not stated.
05Can 7475 be welded?
It depends on the alloy and temper. The 5xxx and 6xxx alloys weld readily with a suitable filler; high-strength 2xxx and 7xxx alloys are generally not arc-welded. Ask for welding advice for your alloy.

An EN 10204 3.1 mill test certificate showing the alloy and temper, lot number, chemistry and mechanical properties.
07Can another alloy replace 7475?
Alloys of the same family are comparable, not identical. Strength, corrosion resistance, weldability and formability differ, so confirm any substitution with your engineer.
08Can 7475 plate be cut to size?
Yes. Plate can be sawn or waterjet cut to your drawing; send the drawing, quantities and tolerances with your enquiry.
09Which sizes are available?
Availability depends on the alloy, temper and thickness; send the thickness, width and length you need and sizes will be confirmed at quotation.
10How do I get a price and delivery date?
Send the alloy and temper, thickness, size or cutting drawing, quantity, destination and required date through the enquiry form below, by WhatsApp or by phone.
