铝合金在飞机上主要是用作结构材料，如：蒙皮、框架、螺旋桨、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.
航天航空用铝合金铸件
Aluminum alloy castings for Aeronautics and Astronautics
在现代飞机结构件中，利用了1500～2000种铝铸件，根据飞机不同的使用条件和部位，主要用了三种基本的铝合金：即高强铝合金、耐热铝合金、耐蚀铝合金。
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、高强铝合金主要用于飞机机身部件、发动机舱、座椅、操纵系统等，
1. High strength aluminum alloy is mainly used for aircraft fuselage components, engine compartment, seat, control system, etc.
2、耐热铝合金零件主要用于靠近电动机的机舱、空气交换系统等，
2. Heat resistant aluminum alloy parts are mainly used for engine room near the motor, air exchange system, etc.
3、耐蚀铝合金具有足够高的性能指标，其强度、塑性、冲击韧性、疲劳性能和可焊性都很好，主要具有耐蚀性，这样就可用于水上飞机。
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.
航天航空用大型挤压型材主要有：整体带筋壁板、工字大梁、机翼大梁、梳状型材、空心大梁型材等。主要用作飞机、宇宙飞船等航天航空器的受力结构部件以及直升飞机异形空心旋翼大梁和飞机跑道等。
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.
铝合金厚板是现代航天航空工业重要的结构材料，其广泛应用于飞机框架、整体壁板、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.
