鋁合金在飛機上主要是用作結構材料，如：蒙皮、框架、螺旋槳、油箱、壁板和起落架支柱等。
Aluminum alloys are mainly used as structural materials in aircraft, such as skins, frames, propellers, fuel tanks, panels and landing gear struts.
航天航空用鋁合金鑄件
Aluminum alloy castings for Aeronautics and Astronautics
在現代飛機結構件中，利用了1500～2000種鋁鑄件，根據飛機不同的使用條件和部位，主要用了三種基本的鋁合金：即高強鋁合金、耐熱鋁合金、耐蝕鋁合金。
In the modern aircraft structure, 1500~2000 kinds of aluminum castings are used. According to the different operating conditions and parts of the aircraft, three basic aluminum alloys are used mainly: high strength aluminum alloy, heat-resistant aluminum alloy, and corrosion resistant aluminum alloy.

1、高強鋁合金主要用于飛機機身部件、發動機艙、座椅、操縱系統等，
1. High strength aluminum alloy is mainly used for aircraft fuselage components, engine compartment, seat, control system, etc.
2、耐熱鋁合金零件主要用于靠近電動機的機艙、空氣交換系統等，
2. Heat resistant aluminum alloy parts are mainly used for engine room near the motor, air exchange system, etc.
3、耐蝕鋁合金具有足夠高的性能指標，其強度、塑性、沖擊韌性、疲勞性能和可焊性都很好，主要具有耐蝕性，這樣就可用于水上飛機。
3. Corrosion resistant aluminum alloy has high performance index, its strength, plasticity, impact toughness, fatigue property and weldability are very good, mainly with corrosion resistance, so it can be used for water aircraft.
航天航空用大型擠壓型材主要有：整體帶筋壁板、工字大梁、機翼大梁、梳狀型材、空心大梁型材等。主要用作飛機、宇宙飛船等航天航空器的受力結構部件以及直升飛機異形空心旋翼大梁和飛機跑道等。
Large extruded profiles for aerospace include: integral reinforced bar panels, I-beam, wing girders, comb shaped profiles, hollow beam profiles, etc. It is mainly used for aircraft, spacecraft and other aerospace structural components, as well as helicopters special-shaped hollow rotor girder and aircraft runway.
鋁合金厚板是現代航天航空工業重要的結構材料，其廣泛應用于飛機框架、整體壁板、起落架、蒙皮等。
Aluminum alloy thick plate is an important structural material in modern aerospace industry. It is widely used in aircraft frame, integral panel, landing gear, skin and so on.
