Aerospace Aluminium Alloy Plate Sheet¹

Product Description Aerospace Aluminium Alloy Plate Sheet The 7 ××× system alloy is an aluminum alloy with Zn as the main alloy element, which is a heat treatment to strengthen the aluminum alloy. The alloy is Mg, Al-Zn-Mg alloy, alloy has good thermal deformation, quenching range, can get high strength heat treatment in the appropriate conditions, can be welding performance is good, generally have good corrosion resistance, stress corrosion tendency is Aluminum Alloy weldable high strength.Al-Zn-Mg-Cu alloy is developed by adding Cu in Al-Zn-Mg alloy on the basis of its strength is higher than 2××× series alloys, commonly known as the Aluminum Alloy ultra high strength, the yield strength of the alloy is close to the tensile strength, yield strength and tension strength rate high, strength ratio is very high, but the plastic and high temperature strength is low, should be at room temperature 120oC below, use of force bearing structure, easy processing, good corrosion resistance and high toughness.7xxx alloy series, because of its long history and varieties of materials, including sheet metal, aluminum plate, medium plate, heavy plate, forgings and extruded parts, has been series of materials and heat treatment. It has been the most widely used high-strength aluminum alloy. The 7175 alloys developed later are special forged alloys, and 7475 are mainly used in the manufacture of thin plates and thick plates. 7475 alloy is the best alloy in the 7075 series with damage tolerance. Chemical Composition of 7×××Aluminum AlloyAlloyZnMgCuCrZrTiSiFe7075 Series70755.0~6.12.1~2.91.2~2.00.18~0.28--≤0.40≤0.5071755.0~6.12.1~2.91.2~2.00.18~0.28--≤0.15≤0.2074755.2~6.21.9~2.91.2~1.90.18~0.25--≤0.10≤0.127050 Series70505.7~6.71.9~2.92.0~2.60.040.08~0.15-≤0.12≤0.1570105.7~6.72.1~2.61.5~2.00.040.11~0.17-≤0.12≤0.1571505.9~6.92.0~2.71.9~2.50.040.08~0.15-≤0.10≤0.1570557.6~8.41.8~2.32.0~2.60.040.08~0.15-≤0.10≤0.157049 Series70497.2~8.22.0~2.91.2~1.90.1~0.220.25 Zr+Ti≤0.25≤0.3571497.2~8.22.0~2.91.2~1.90.1~0.220.25 Zr+Ti≤0.15≤0.2072497.5~8.21.9~2.61.3~1.90.12~0.180.25 Zr+Ti≤0.10≤0.12        ≤0.157B50Series7B506.0-7.02.0-2.81.8-2.60.040.08-0.160.10.120.157A55Series7A557.5-8.51.8-2.81.8-2.50.040.08-0.200.10-0.250.10 0.10 Alu Sheet SpecificationAlloyTemperThickness(mm)Width (mm)7075T6,T73,T76,T740.5-3.5800-2600747570503.5-6.0800-29007B50Alu Plate SpecificationAlloyTemperThickness(mm)Width (mm)7075T651T7351T7651T7451T77516-12800-29007475705012-250800-38007B507A55Alu Sheet Mechanical PropertiesAlloyTemperTypicalThicknessRm(Mpa)Tensile StrengthRp0.2(Mpa)Yield Stregth(%)ElongationStangard7075T60.5-6.058050012SAE AMS-QQ-A-250/127075T730.5-6.048040512SAE AMS-QQ-A-250/127075T760.5-6.049041012SAE AMS-QQ-A-250/127475T610.5-6.054046012SAE AMS 40847475T7610.5-6.051043512SAE AMS 40857050T760.5-6.053548510SAE AMS 4243Alu Plate Mechanical PropertiesAlloyTemperTypicalThicknessRm(Mpa)Tensile StrengthRp0.2(Mpa)Yield Stregth(%)ElongationStangard7075T6516.0-225.057049510SAE AMS 40457075T73516.0-150.050042010SAE AMS 40787475T76516.0-50.051043510SAE AMS 40897050T74516.0-225.053046010SAE AMS 40507050T76516.0-100.055048010SAE AMS 42017B50T61516.0-50.060055012-7B50T77516.0-100.059054010-7A55T77516.0-50.063560510-Application parts and typical parts:The thick section of the main structure of high load, such as the manufacture of fuselage frame and bulkhead, wing skin, extrusion reinforcing rod, stringers and ribs, forging parts, gear support member, beams, strengthening panels, flanges, important joints etc.. Detailed Photos
