When designing aircraft and other equipment with extremely high detail requirements, nothing can go wrong, so metals used in aerospace are required to perform exceptionally well at all times. Some of the specific properties required of materials used in the aerospace industry include: high strength, heat resistance, long life, fatigue resistance, and wear resistance. Weight is also very important, especially when considering aerodynamics and fuel.
1. Lightweight: Aluminum is much lighter than steel, which is critical to the aerospace industry because reducing weight can improve fuel efficiency, reduce costs and increase payload capacity.
2. High strength: Aeroplane aluminium is designed to withstand the extreme stresses of flight and space travel, ensuring the safety and reliability of aircraft and spacecraft.
3. Corrosion resistance: Aluminum naturally forms a protective oxide layer when exposed to air, which makes it resistant to corrosion. This is critical for aerospace applications, as exposure to moisture, high altitude and space conditions can cause severe damage to the material.
4. Formability: The aluminum alloy is ductile and can be easily formed into the complex geometric shapes required for aircraft fuselages, wings and structural components.
Although 6000 series aluminum alloys such as 6061 and 6063 have low strength, they have good ductility and are often used in fuselage frames and outer frame structural parts, bolt assemblies, and door and window frames.
7000 series aluminum alloys such as 7075 are the strongest of all series of aluminum alloys. They are usually used where high fixing force is most needed. This alloy is mainly used in the windward part of the entire aircraft, such as the upper outer plate and longitudinal beams of the wing, the tail, the wing ribs and the reinforcement of the fuselage bulkhead. In addition, it is also often used in gears and shafts, instrument shafts and turbines.
One of the key reasons aerospace-grade aluminum is vital in aircraft design is its lightweight properties. In commercial aviation, fuel costs are one of the largest operating expenses. By using lightweight materials such as aluminum, airlines can significantly reduce the overall weight of their aircraft, thereby improving fuel efficiency.
The introduction of advanced aluminum alloys has enabled manufacturers to design lighter, more fuel-efficient aircraft. For example, Boeing uses a higher percentage of aluminum in its structures to reduce weight while maintaining the strength and durability required for long-distance flights.
The strength-to-weight ratio of aerospace-grade aluminum makes it ideal for high-stress applications in aircraft. Components such as wings, fuselages, and engine mounts require materials that can withstand the forces experienced during takeoff, flight, and landing. The ability to combine lightness with strength makes aluminum a material of choice for aerospace engineers, as it allows for the creation of strong structures without adding excessive weight.
The natural corrosion resistance of aerospace-grade aluminum is essential to the life of an aircraft. Commercial and military aircraft are exposed to extreme conditions, including high altitudes, varying temperatures, and constant moisture. By using rust- and corrosion-resistant aluminum alloys, aircraft manufacturers can ensure their products have a longer service life, thereby reducing maintenance costs and improving passenger safety.
