Aluminum alloy disk 7 series

7000 series aluminum alloys are used in many industries, including aerospace, national defense and racing. The following are some typical 7 series alloy models for Chalco’s aluminum forgings. 7A04 alloy is an Al-Zn-Mg-Cu heat treatment strengthening alloy. Its strength is higher than that of duralumin. Its yield strength is close to tensile strength, and its plasticity is low. 7A04 aluminum forgings are widely used in the main load-bearing parts of aircraft structures, such as girders, trusses, diaphragms, skins, wing ribs, joints, landing gear parts, etc. It can also produce various semi-finished products, such as plates, strips, profiles, bars, wallboards, pipes, wires, free forgings and die forgings. 7050 aluminum alloy has high fatigue limit, good toughness, good stress corrosion resistance, good hardenability, and high strength. It has general weldability and good cutting performance. 7050 is mainly used for high strength, good fracture toughness, and high stress corrosion cracking resistance and spalling corrosion of the main bearing structural parts, such as aircraft structure with thick plates, extrusions, free forgings and die forgings, such as aircraft structure with thick plates, extrusions, free forgings and die forgings, including fuselage frames, partitions, wing beams, landing gear support parts and rivets. 7150 T77 aluminum forging is an improved 7050 alloy with high strength and good corrosion resistance. It is mainly used for large passenger aircraft upper wing structure, fuselage plate beam flange, upper outer plate main wing longitudinal beam, fuselage reinforcement, keel beam and seat guide rail.
