Aircraft Aluminum Sheet
Aircraft Aluminum Sheets refer to those high-performance aluminum alloy plates specially used in the aviation industry. These aluminum plates play a vital role in the aerospace field with their light weight, high strength, good corrosion resistance and mechanical properties. Aircraft Aluminum Sheets usually contain a variety of aluminum alloy series, such as 2 series, 6 series, 7 series, etc., each of which has unique properties and application ranges.
Specifications of Common Aircraft Aluminum Sheet
| Alloy | Strength level | Application Range | Corrosion Resistance | Tensile Strength | Elongation | Density | Other Characteristics |
| 7075 | Ultra-high strength | Aircraft structural parts, landing gear | Good | 505-620 MPa | 12-15% | 0.98 g/cm³ | Poor welding performance, special protection required |
| 2024 | Medium-high strength | Aircraft structural parts, brackets | Fair | 490-527 MPa | 12-15% | 0.96 g/cm³ | Contains copper and magnesium, which increases brittleness |
| 6061 | Medium strength | Aerospace, automobile, electronics | Good | 275-350 MPa | 16-20% | 0.97 g/cm³ | Better performance after heat treatment |
| 7050 | High strength | Large structural parts | Good | 549-620 MPa | 12-16% | 0.98 g/cm³ | Strong resistance to corrosion and cracking |
Features of Aircraft Aluminum Sheet
Aircraft Aluminum Sheets play a vital role in the aerospace field because they directly affect the performance, weight and safety of aircraft.
1. High strength and lightweight
Aviation aluminum plates such as 7075 aluminum alloy have a tensile strength of up to 560MPa and an elongation of 6%, which allows it to withstand high loads while maintaining its lightweight characteristics, which is crucial for aircraft to reduce their own weight, improve fuel efficiency and carrying capacity.
2. Corrosion resistance
Aviation aluminum plates usually have good corrosion resistance, especially for seawater and most chemical media, which allows them to work for a long time in harsh environments without being easily corroded.
3. Fatigue resistance
Aviation aluminum plates also have good fatigue resistance, which means they can withstand repeated loads without breaking, which is extremely important for the safe operation of aircraft under complex flight conditions.
4. Processing performance
Aviation aluminum sheets can be made through a variety of processing techniques, including forging, rolling, extrusion, etc., which enables them to form complex three-dimensional shapes and parts to meet the strict requirements of material shapes in the aerospace field.
Application
Aircraft Aluminum Sheets are widely used in the aerospace field due to their excellent properties such as light weight, high strength and corrosion resistance. The following will introduce in detail the specific application of Aircraft Aluminum Sheet:
Main application parts on aircraft:
- Fuse skin: This is one of the most widely used parts of aluminum alloy on aircraft. Aluminum alloy skin can not only reduce the weight of the aircraft and improve flight efficiency but also has good formability and corrosion resistance.
- Wing: The wing is a key component for aircraft to generate lift. Aluminum alloy wings have high strength, high stiffness and good fatigue performance, and can withstand the huge stress generated during flight.
- Tail: The tail is used to control the flight attitude of the aircraft. The aluminum alloy tail has the characteristics of light weight, good rigidity, and corrosion resistance.
- Landing gear: The landing gear is the part that contacts the ground when the aircraft takes off and lands. Aluminum alloy landing gear has good shock absorption and wear resistance.
- Internal structure: The internal structure of the aircraft, such as beams, girders, bulkheads, etc., also widely uses aluminum alloy materials.
