Aluminum Alloy Sheet For Aircraft

What is aircraft aluminum sheet

The aircraft aluminum sheet is an ultra-high-strength deformed aluminum alloy, which is currently widely used in the aviation industry. It is of good mechanical and processing properties, good plasticity after solution treatment, and good heat treatment strengthening effect.

In addition, the aircraft aluminum sheet metal, as an ideal structural effect, is of light weight, having occupied the leading position of current aviation materials.

Aluminium Alloy Plate In Aircraft & Aerospace Application

7XXX Series Alloys – (heat treatable – with ultimate tensile strength of 32 to 88 ksi) These are the aluminum / zinc alloys (zinc additions ranging from 0.8 to 12.0%) and comprise some of the highest strength aluminum alloys. These alloys are often used in high performance applications such as aircraft, aerospace, and competitive sporting equipment. Like the 2xxx series of alloys, this series incorporates alloys which are considered unsuitable candidates for arc welding, and others, which are often arc welded successfully. The commonly welded alloys in this series, such as 7005, are predominantly welded with the 5xxx series filler alloys.

7xxx Series
The airframe of a typical modern commercial transport aircraft is 80 percent aluminum by weight. Aluminum alloys are the overwhelming choice for the fuselage, wing, and supporting structures of commercial airliners and transport aircraft. Structural components made of fabricated wrought aluminum (forged, machined and assembled parts). Attention is now focused toward aluminum casting technology, which offers lower manufacturing costs, the ability to form complex shapes and the flexibility to incorporate innovative design concepts.

Aluminum was used as the primary propellant for the space shuttle’s solid rocket booster motor because it has a high volumetric energy density and is difficult to ignite accidentally.

The applications of aircraft aluminum alloy

1. 2A12 and 2024 aluminum plate with high fracture toughness and low fatigue crack growth rate, is a commonly used material for the fuselage and wing skins. 2A12 aluminum plate is also suitable for aircraft structural parts (such as skin, skeleton, rib beam, bulkhead, etc.

2. 7075 aircraft aluminum is of high strength, which can be used in the bomber, but its resistance to stress corrosion and spalling corrosion is poor.

3. 6061 aluminum plate is an earlier 6XXX series aluminum alloy used in aviation. It has good corrosion resistance and excellent weldability, but its strength is moderate.

4. 7055 aircraft aluminium sheet is developed by increasing the content of Zn and Cu elements on the basis of 7050 aluminum alloy, featuring low density, high strength, good processing performance, good welding performance and good stress corrosion resistance.
