Aluminum alloy applications

Weden Metal Co.,Limited | Updated: Feb 26, 2018

  All kinds of aircraft are aluminum alloy as the main structural material. Aircraft skin, beams, ribs, stringers, bulkheads and landing gear can be made of aluminum. Depending on the use of the aircraft, the amount of aluminum is not the same. Focus on the economic benefits of civilian aircraft due to cheap aluminum and a large number of uses, such as the Boeing 767 aircraft using aluminum alloy body structure accounts for about 81% of the weight. Military aircraft relatively reduce the amount of aluminum required for good combat performance, such as 35.5% aluminum alloy for the F-15 high-performance fighter with a maximum speed of Mach 2.5. Some aluminum alloy has good low temperature performance, not brittle under -183 ~ -253 [2oc], can work in liquid hydrogen and liquid oxygen environment, it can not afford chemical reaction with concentrated nitric acid and UDMH, has good Of the welding performance, it is a good material for manufacturing liquid rocket. Fuel tank, oxidizer tank, tank compartment, interstage section, tail section and instrument compartment at all levels of Saturn 5 launch vehicle that launch Apollo spacecraft are made of aluminum alloy.

  Space shuttle crew cabin, front fuselage, fuselage, rear fuselage, vertical tail, flaps, aisle and tailplane are made of aluminum alloy. The main structural materials for various artificial earth satellites and space probes are also aluminum alloys.
