Aircraft Grade Aluminum Sheet
Aircraft grade aluminum sheets are used in the construction of various parts of an aircraft, including the fuselage, wings, and other structural components. They are also used in the production of aircraft skins and panels, where their strength and durability are essential for maintaining the structural integrity of the aircraft.
Aluminum alloys make up 75 to 80 % of modern aircraft and have been used for this purpose since the dawn of powered flight.
The reason is that aircraft require strong yet lightweight materials.
Because aluminum aerospace parts are about one third the weight of steel, which allows aircraft to carry more weight and be more fuel efficient than they could be if built with heavier material. In addition, the high corrosion resistance of aluminum is essential for aircraft safety.
Aircraft grade aluminum sheet plate has excellent strength-to-weight ratio, corrosion resistance and other properties that make it suitable for aerospace applications. Some common aluminum alloys used for aircraft grade sheets and plates include:
The following is a detailed introduction to aircraft grade aluminum sheet plate.

7075 aircraft aluminum sheet is a kind of zinc-magnesium aluminum alloy, which is the most common aluminum alloy with the best strength. 7075 t6 aircraft aluminum sheet is one of the strongest commercial alloys, with good mechanical properties and anode reaction.
Aircraft Grade (7075 alloy) Aluminum Sheet
Other tempers of 7075 aircraft aluminum include T651, T7651 and T7351. But it cannot be welded, and its corrosion resistance is relatively poor. In terms of hardness, 7075 aircraft aluminum is the top grade among 7 series aluminum alloys, suitable for making aircraft structures and high-strength accessories.
| Alloy | Si | Fe | Cu | Mn | Mg | Cr | Zn | Zr | Ti | Al |
| 7075 | 0.40 | 0.50 | 1.2-2.0 | 0.30 | 2.1-2.9 | 0.18-0.28 | 5.1-6.1 | – | 0.20 | Remainder |
Because of copper, it is difficult but not impossible to weld.

The three most used are 6061, 7075 and 2024 clad.
6061 is alloyed with magnesium and silicon, is easy to machine and can be easily welded. 7075 has zinc as its main alloy and has high strength, but cannot be effectively welded. 2024 is by far the most popular choice for skins – it’s alloyed with copper and is sandwiched between layers of pure aluminum to prevent corrosion. It also should not be welded.
