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.
