شرح

Aerospace aluminum plate is an ultra-high-strength deformed aluminum alloy currently widely used in the aviation industry.

Aerospace grade aluminum refers to aluminum alloys that are specifically designed and tested for use in the aerospace industry. These alloys are chosen for their high strength, چگالی کم, and resistance to corrosion, making them ideal for aircraft and spacecraft components

در مقایسه با آلیاژهای آلومینیوم معمولی, the aluminum alloys used in aircraft have higher requirements for strength, سختی, سختی, مقاومت در برابر خستگی, and plasticity.

Aviation aluminum alloy has good mechanical and processing properties, good plasticity after solution treatment, and good heat treatment strengthening effect. It generally has high strength and good toughness below 150°C (or even higher), making it an ideal aviation structural material.

Some popular aerospace aluminum alloy are 2024, 2324, 2524 و 7050, 7055, 7075, 7475 و 6061 sometimes was used for non-structural parts.

Typical Products of Aluminum Sheet

Aluminum alloys are widely used in launch vehicles in the aerospace field. The main grades are 7075, 20X4, 2219, و غیره. The engine device, main components, rotary table, remote control parts, و غیره. are mainly aluminum alloy 7075. مثلا, the liquid oxygen tank is mainly 2219. 20X4 is mainly used for satellite streamlined outer covers and temperature control valve components. علاوه بر این, the frame of the manned aircraft is made of 2024 و 7075 aluminum alloys because these two aluminum alloys have high strength, light weight and thin thickness. Aluminum alloy sheets are also frequently used in these objects, such as protective panels, safety devices, پروانه ها, و غیره.

How is Aerospace Aluminum Plate Different from Regular Aluminum?

Aerospace aluminum plate is different from regular aluminum in several ways:

1. ترکیب آلیاژی: Aerospace aluminum plate is typically made from high-strength aluminum alloys that are specifically designed for aerospace applications. These alloys usually have a higher content of elements like copper, فلز روی, منیزیم, and manganese, which enhance the strength and durability of the material. Regular aluminum, از سوی دیگر, may have a lower alloy content and is often used for general-purpose applications.

2. Strength and toughness: Aerospace aluminum plate is engineered to have superior strength and toughness compared to regular aluminum. It undergoes various heat treatment processes to enhance its mechanical properties, making it capable of withstanding high stress and loads experienced in aerospace applications. Regular aluminum may not possess the same level of strength and toughness.

3. وزن: Aerospace aluminum plate is lightweight compared to regular aluminum. The aerospace industry emphasizes the importance of reducing weight to improve fuel efficiency and increase payload capacity. از این رو, aerospace aluminum plate is designed to be lightweight while maintaining its structural integrity. Regular aluminum may have a higher weight due to lower strength requirements.

4. Quality control: Aerospace aluminum plate undergoes stringent quality control processes to ensure its performance and reliability. It needs to meet various industry standards and specifications, such as those set by the International Aerospace Quality Group (IAQG). Regular aluminum may not be subjected to the same level of quality control measures.

5. Cost: Aerospace aluminum plate is generally more expensive than regular aluminum due to its specialized composition, manufacturing processes, and quality requirements. The aerospace industry demands high-performance materials, which often come at a higher cost. Regular aluminum, being more widely used and less specialized, tends to be more affordable.
