Aerospace aluminum profiles: There are mainly three types of profiles: high-strength, heat-resistant, corrosion-resistant. The profiles used vary depending on the different parts of the aircraft, such as the fuselage components, control systems, engine compartments, seats, which require the use of high-strength aluminum profiles with higher hardness strength; If the engine compartment air exchange system close to the motor continue to heat up, heat-resistant profiles should be used; The wall panels, beams, stringers, propellers on aircraft wings require corrosion-resistant aluminum profiles to be made; The forged rings of rockets the wall panels of spacecraft require higher requirements, requiring the use of corrosion-resistant ultra-high strength materials ××× Series 7 ××× Made profiles.
