Product Description 7A09 aluminum alloy sheet round bar forgings Ultra high strength Aluminum Alloy 7A09 alloy is Al-Zn-Mg-Cu, the strength of 7A09-T6 alloy 7A09 aluminum alloy sheet round bar forgings is the highest, the aviation industry with one of the highest strength Aluminum Alloy deformation, the composition ratio of 7A04 alloy more superior performance, so it has better, get more extensive application in aircraft manufacturing, used in the manufacture of various important components of the force,7A09 aluminum alloy sheet round bar forgings have been widely used in aircraft, transport aircraft, and medium bomber trainer, for the production of the front landing gear, wing, fuselage connection frame, beam, pillar, partitions, floors, main beam joints and tail on the wall, the working cylinder hydraulic system, hydraulic oil tank of the movable rod inside and outside the tube, and other key components. Because of its high strength, the weight reduction effect is good and the safety of the aircraft is improved.Chemical Composition of 7A09 alloy AlloySiFeCuMnMgCrNiZnTiZrOthersAlEachTotal7A090.500.501.2~2.00.152.0~3.00.16~0.30-5.1~6.10.10-0.050.15RemainderThe semi-finished products of 7A09 alloy are 7A09 aluminum alloy sheet round bar forgings. The alloy has satisfactory fracture toughness in T6 state. The strength and yield strength in T73 over aging state are lower than that in T6 state, but the alloy has excellent stress corrosion resistance and high fracture toughness. The T6 state material has good resistance to exfoliation and corrosion. When the temperature rises, the strength of the alloy decreases, and the long-term use temperature should not exceed 125 oC. AlloyAlloy seriesMain featuresσb Value/MPaWorking Temperature/oC7A097075(American)At present,7A09 aluminum alloy sheet round bar forgings is one of the most powerful domestic aluminum alloys, which can produce various specifications of plate, bar, profile, thick pipe fittings and forgings. There are four heat treatment states of T6, T73, T76 and T74. The chemical composition is better than that of 7A04 alloy, and its comprehensive properties are better. Under the condition of annealing or solid solution heat treatment, it has good forming properties at normal temperature. The forming performance is lower in the solid solution heat treatment and artificial aging condition, but with the increase of temperature, the forming properties are improved. Resistance welding can be carried out, and it is not suitable for welding. 455~540<1256 Physical Property of 7A09 AlloyAlloyTypeTemperδ Size /mmσb/MPaσp 0.2/MPaδ %KIC or KCStandard7A09Aluminum sheetT61.0~2.5LT:480LT: 410LT:7-GJB 2053-1994>2.5~6.5LT:490LT: 420LT:7T92.0~4.0LT:520LT: 460LT:6T621.0~2.5LT:470LT: 400LT:7>2.5~6.5LT:480LT: 410LT:7Aluminum plateT67~10LT:490LT: 420LT:7-GJB 2662--1996T627~10LT:480LT: 410LT:7H112--T67~10LT:490LT: 410LT:6>10~25LT:490LT: 410LT:4>25~40LT:490LT: 410LT:3T635~40ST 390-2Pre-streching aluminum plateBCSYU>1.0~6.0LT:540LT:460LT:9-GJB 1741--1993>6.0~10.5LT:540LT:470LT:7Extuded aluminum barT65~22L:490L:370L:7-GJB 2054---1994>22~150L:530L:400L:6H112---T6>150~250L:500L:400L:4High strength aluminum barH112---T620~100L:550L:450L:6>100~150L:530L:430L:6T620~150L:550L:450L:6Extruded aluminum barT73≤38L:485L:420L:7-Q/6S 824--1997Q/S 321--1991>38~76L:475L:410L:7>76~125L:470L:395L:6T74≤22L:490L:375L:7Q/6S 1352--1997Q/S 320--1991>22~160L:530L:405L:6>160L:510L:405L:5Extruded aluminum profileT6≤10.0L:500L:440L:6 GJB 2507--1995>10.0L:540L:460L:6 T74≤10.0L:500L:440L:6-Q/6S 1490--1999Extruded aluminum tubeT625~120L:530L:400L:6-GJB 2381--1995>120~250L:510L:400L:5Die forgingsT6-L:530L:400L:6LT:450-LT:4ST:425-ST:3Free forgingsT6-L:510L:420L:6LT:440-LT:3ST:420-ST:2Die forgingsT73-L:455L:385L:7 GJB 1057--1990GJB 2351--1995LT:440LT:370LT:4ST:425-ST:3Fee forgingsT73-L:455L:385L:6LT:440LT:370LT:4ST:420-ST:2Die forgingsT74weight≤30kg L:510L:430L:6 GJB 2351--1995LT:450-LT:4ST:425-ST:3weight>30kg L:510L:430L:6LT:450-LT:4ST:425-ST:2Die forgingsT74 weight≤30kg L:490L:410L:6LT:440-LT:3ST:420-ST:2weight>30kg L:490L:410L:5LT:440-LT:3ST:420-ST:2 AlloyTemperAircraft modelsApplication parts and typical parts7A09Aluminum sheet: T6,T9,T62Aluminum plate:T6, T62Aluminum profile: T6,T74Aluminum forgings:T6,T74,T73,Z9, Z10,Z11 etc.,All kinds of beams, frames, baffles, panels, ribs, joints, skins, front landing gear, actuating cylinder, arm, pillar and so on.
