Aluminum alloy in the manufacture of spacecraft

In recent years, due to frequent take-offs and landings, small passenger aircraft have been used in more ground work (contact with ground equipment, vehicles, and refurbishment work), and aluminum alloys are not used in carbon fiber reinforced composites. If carbon fiber reinforced composites are used, it is very difficult to repair damage during use, and it is difficult to visually observe the extent of damage, etc., so it is necessary to use a specific device such as a dedicated ultrasonic flaw detector. The successful launch of "Shenzhou XII" once again proves the great development of China's space engineering. The manufacturing of spacecraft has once again become a hot spot for people to chase. Why should aluminum alloy be used for the manufacture of spacecraft? What are the better aircraft aluminum alloys? Let's find out together today.

2024 aviation aluminum alloy is used for aircraft structural parts. 2048 aviation aluminum alloy is mainly used to manufacture aerospace structural parts and weapon structural parts. 2218 is mainly used in aircraft engine and diesel engine pistons, aircraft engine cylinder heads, jet engine impellers and compressor rings. 2219 is used in space rocket welding oxidizer tanks, supersonic aircraft skins and structural parts. The 7049 is used in aircraft and missile parts such as landing gear cylinders and extrusions. 7050 aviation aluminum alloy is used for medium and thick plates, extrusions, free forgings and die forgings of aircraft structural parts. 7178 aerospace aluminum alloy is used to manufacture aerospace vehicles required for high compressive yield strength parts. 7475 is used in fuselage plates, wing frames, stringers, etc. The 7A04 is used for aircraft skins, screws, and stressed components such as girder stringers, partitions, wing ribs, and landing gear.

Well, I'll explain it to you here today, thank you for watching.
