Why is Aluminium Used To Build Aircraft

Why is aluminium used to build aircraft, due to their high specific strength, good forming and processing properties, aluminum are the main structural materials of aircraft, such as skins, frames, propellers, fuel tanks, siding and landing gear struts. Classified by alloy composition, aircraft grade aluminum is mainly 2000 series and 7000 series. According to the disclosure of Haomei Aluminum, the aluminum alloys used in build aircraft structures in the world today are mainly high-strength 2000 series (2024, 2224, 2324, 2424, 2524, etc.) and ultra high strength 7000 series (7075, 7475, 7050, 7150, 7055, 7085, etc.)

Why is aluminium used to build aircraft? That is because compared with traditional aluminum alloys, aluminum lithium alloys have higher specific strength and specific stiffness, and have stronger damage tolerance, fatigue resistance, and radiation resistance. The use of aluminum lithium alloys can greatly improve the life of the aircraft. The third-generation aluminum-lithium aircraft grade aluminum alloy is applied to the fuselage skin, long stringer, and floor beam structure, and the amount reaches 7.4% of the weight of the fuselage structure. The application of composite materials realizes the integration and lightweight of the airframe structure, and the amount of composite materials reaches 11.5% of the weight of the airframe structure.

Above are the reasons why is aluminium used to build aircraft. For aircraft grade aluminium manufacturers, the aluminum alloy medium and heavy plate roller hearth type solution heat treatment furnace is used for the solution quenching treatment of 7xxx, 2xxx, 6xxx aluminum alloy medium and thick plates with high performance requirements and high surface quality for aviation and aerospace. This equipment is a necessary high-end and high-precision equipment for the production of pre-stretched panels for large aircraft, ships and weapons.
