7150 Aluminum Alloy Used in Aviation

The flying equipment whose flying height is within 100 km from the ground is called aircraft, and the various deformed aluminum alloys and cast aluminum alloys used to manufacture aircraft are all aviation aluminum. Among them, aircraft plates, profiles, wires, etc. are mostly processed by deformed aluminum alloys.

7150 aluminum alloy was developed in the late 1970s, featuring super strength, high toughness and excellent corrosion resistance. The birth of 7150 aluminum for the first time achieved the goal of aluminum alloy having good corrosion resistance and high strength at the same time.

7150 aluminum alloy is widely used in aerospace plates, profiles, castings, etc., which is used to make high-strength structural parts of aircraft, such as aircraft wing outer spars, main landing gear beams, nose landing gear action tubes, vertical tail joints, rocket jet pipe structure.

The aluminum parts of the ARJ21 aircraft account for three-quarters of the aircraft's net weight. Among them, the upper wing upper wall panel is made of 7150-T7751 aluminum alloy. At the same time, 7150 aluminum alloy is also used to manufacture wing beams, fuselage stringers, fuselage frames, bulkheads, wing upper stringers, and wing ribs and spars, etc.

The China’s C919 airplane has selected a large number of fourth-generation aluminum alloys, such as 7050-T7452, 7150-T77511 and so on. 7150 aluminum alloy is also used in other aircraft such as Xinzhou 60 branch line passenger aircraft, Yun-20 heavy military transport aircraft, large amphibious aircraft AG6000, various fighter jets and other military aircraft.

Different heat treatment processes has different effects on the properties of 7150 aluminum thick plate. It is found that after T77 treatment, the vertical and horizontal properties of the 7150 aluminum sheet gradually approach as the solution time increases. The anisotropy of the alloy is the lowest at 5 h. Welcome to leave message below to inquire what you need.
