What is aircraft aluminum sheet?

Aircraft aluminum sheets (aviation aluminum plate) is an aluminum-magnesium alloy that has been specially treated by high-temperature oxidation and other special treatments. It can withstand thousands of degrees of high temperature or blue impact. It is a high-strength and corrosion-resistant aluminum product that is lightweight and durable. , Since it was first used in high-tech fields such as aviation equipment manufacturing, it is called “aircraft aluminum sheet.”

Aircraft aluminum solid plates are specially treated, can withstand thousands of degrees of high temperature or strong impact, and have good performance. Together with titanium alloys, they are widely used in high-tech fields such as aviation equipment manufacturing.

Characteristics of aluminum sheet for aircraft

Because alumina is a white powdery substance, it is a covalent compound with a melting point of 2050°C, a boiling point of 3000°C, and a true density of 3.6g/cm3. It has poor fluidity and is insoluble in water, and soluble in molten cryolite. It is the main raw material for aluminum electrolysis production. It has high hardness, and high strength, but is lightweight. After being oxidized at high temperatures, the aviation aluminum plate completely inherits the characteristics of alumina, making the aviation aluminum plate resistant to high pressure, impact resistance, welding non-breaking, and corrosion resistance. Due to the shortcomings of steel plate rusting and peeling under the erosion of sunlight or water, oxidized aircraft aluminum plates can completely solve this problem. It has made contributions to the aerospace industry and the field of space research.

The most commonly used alloy type of aluminum sheet for aircraft

An airplane aluminum plate is an aluminum-magnesium alloy plate, the surface is oxidized. It is an aluminum product with high strength and anti-corrosion performance, and it is lightweight and durable. The most used is the 7075 alloy aluminum plate, which is characterized by good plasticity after solution treatment, particularly good heat treatment strengthening effect, high strength below 150°C, and particularly good low-temperature strength; poor welding performance; stress Corrosion and cracking tendency; need to be used with aluminum clad or other protective treatment. Two-stage aging can improve the alloy’s ability to resist stress corrosion cracking. The plasticity in the annealed and as-quenched state is slightly lower than 2A12 in the same state. Slightly better than 7A04. The static fatigue and notch sensitivity of the sheet is better than 7A04. The stress corrosion resistance of the sheet is better than 7A04. Among them, 7075T651 is especially the top grade, which is known as the best aluminum alloy. Excellent product, high strength, far better than mild steel. Aviation aluminum plate is suitable for the national standard of aluminum plate and strip (GB/T 3880-2006) and is suitable for the unified standard of aluminum alloy plate and strip material.

What type of aluminum alloy is used on the aircraft?

2024 alloy​ T3 Aluminum Sheet

This is the most common of the high-strength aluminum alloys. It is of high-grade aircraft quality. The 2024-T3 aluminum sheet is thought of as an aircraft alloy because of its strength and it also has excellent fatigue resistance. Welding is generally not recommended. Typical uses for 2024-T3 Alclad aluminum sheet are fuselage and wing skins, cowls, aircraft structures, and also for repair and restoration because of its shiny finish (2024-T3 Alclad).

3003 H14 Aluminum Sheet

Most widely used of aluminum alloys, pure aluminum with manganese added for strength, approx 20% stronger than the 100 series. The 3003-H14 aluminum sheet has great workability and may be deep drawn, spun, welded or brazed. 3003 aluminum sheet is NON-heat treatable. This aluminum sheet is widely used for cowls and baffle plating.

5052 H32 Aluminum Sheet

This one has the highest strength in the NON-heatable alloy series. It is not structural. 5052 aluminum sheet has higher fatigue strength than most alloys. 5052 aluminum sheet has excellent corrosion resistance, particularly in marine applications, and has excellent workability. 5052 aluminum sheet is commonly used to build fuel tanks.

5083 aluminum sheet – Aluminum plate for aircraft welding parts

5083 aluminum sheet belongs to Al-Mg-Si aluminium alloys. Its main contents are Magnesium and Silicon except for Aluminium. Over 4.0% of Magnesium enables 5083 aluminum sheet to have excellent resistance to correction, and are easily to welded. By adding copper, 55083 aluminum sheet has 28% Electrical conductivity. 5083 aluminum sheet also has good forming characteristics for either hot or cold working. But hardening is accomplished by means of cold working only. Besides, 5083 aluminum sheet does have good strength but non-heat-treatable.

6005 aluminum plate – Aluminum plate for aircraft fuel tank

6005 aluminum alloy belongs to Al-Mg alloy, which is a widely used anti-rust aluminum. The advantages of good weldability and cold workability are often used for transportation vehicles, aircraft fuel tanks and oil pipes. The aluminum plates used are mostly 6005 aluminum plates. The 6005 aluminum plates produced by Mingtai Aluminum have high strength, especially fatigue resistance Requirements for aluminum plate materials for aircraft fuel tanks.

6061 T6 Aluminum Sheet

This alloy has very good corrosion resistance and finishing ability, welding goes without any problems too. The strength level of 6061-T6 aluminum sheet is about that of mild steel. 6061-T6 aluminum sheet can be fabricated by most of the commonly used techniques. Typical uses are aircraft landing mats, truck bodies and frames, structural components, and more.

7075 Aluminum Sheet – Aluminum sheet for aircraft structural parts

Aircraft manufacturers use high-strength alloys (principally alloy 7075) to strengthen aluminum aircraft structures. Aluminum alloy 7075 has Copper (1.6 %), Magnesium (2.5 %) and zinc (5.6 %) added for ultimate strength, but the copper content makes it very difficult to weld. On the other hand it anodizes really beautifully. 7075 has the best machinability and it will result in a very nice finish.

All material meets ASTM or AMS specifications with ultrasonic testing as required. Test certificates are maintained to ensure full material traceability. Waterjet cut parts for special aluminum plate shapes can be provided with close tolerances and minimal distortion.

Other application fields of aluminum sheet for aviation

In addition to being used in aerospace and aircraft manufacturing, aircraft aluminum sheets can also be used as blow molding (bottle) molds, ultrasonic plastic welding molds, golf ball heads, shoe molds, paper-plastic molds, foam molding molds, dewaxing molds, templates, Fixtures, mechanical equipment, mold processing, and other corrosion-resistant high-stress structural parts.
