Aircraft Aluminum Sheet, Aircraft Grade Aluminum
what is aircraft grade aluminum
Aluminium is a part of our everyday life and it seems like every time we turn around we see things made of aluminium like the foil wrapping your food, the ladder you climb to clear the gutters, the screen door to keep flies out, and your beloved golf ball rod.
But what about the aluminum used in airplanes, is aluminum aircraft the same grade as the aluminum I find in my kitchen? No, it is absolutely different. The requirements for aircraft grade aluminum are very high, so as to ensure the performance, safety and stability of the aircraft. The alloys of aluminum in life are generally 1000 series (pure aluminum) and 3000 series, while the representatives of aircraft grade aluminum are 2024 and 7075 alloys.
When you hear the word aircraft-grade aluminum, its key properties that come to mind are light weight, strength, and corrosion resistance, as all of these properties are essential to the safety of aircraft; in addition, the ability to resist UV damage, making aircraft aluminum grades becomes ideal metal for aircraft structure.
In addition to aircraft applications, aircraft aluminum is also used in spacecraft. Most spacecraft are composed of up to 90% aluminum components, and the application of aircraft grade aluminum in the space station plays a huge role in manned space exploration.
Common aircraft grade aluminum alloy , properties and applications
Common aircraft grade aluminum alloy, properties and applications | ||
| Alloy & Temper | Properties | Application |
| 2024-T3 | The most common high-strength aluminum alloy, although its corrosion resistance is lower than that of 6061, it has excellent fatigue resistance. | This aircraft grade aluminum sheet is commonly used to make fuselages, wing skins, aircraft structures and fairings for most aircraft. It is also ideal for restorations and restorations because of its shiny finish. |
| 6061-T6 | This alloy is known for its high corrosion and finish. It is easy to weld and has the same strength as mild steel | Aircraft Aluminum Sheet 6061-T6 is commonly used to make landing gear for aircraft, trucks and frames and structural components. |
| 5052-H32 | 5052-H32 is a non-heat treatable aluminum alloy with one of the highest strengths in its class. Aircraft Aluminum Sheet is not structural but has high fatigue strength compared to other alloys. It also has excellent corrosion resistance, especially in marine applications. | Its excellent machinability makes this aluminum sheet ideal for the construction of aircraft fuel tanks. |
| 3003-H14 | This aluminum sheet has excellent machinability and is one of the most widely used aluminum alloys. Aircraft Grade Aluminum Sheet is made from a mixture of pure aluminum and manganese. This alloy is also not heat treatable | It's perfect for making cowls in aircraft and baffle plating. |
| 7075-T6 | The alloy is made from a careful mixture of copper, magnesium, and zinc to give it extra strength. However, because of copper, it is difficult but not impossible to weld. Once anodized, it has a beautiful finish and has the best machinability. | The main function of this Aircraft-Grade Aluminum sheet is to strengthen the aluminum aircraft structure |
